There are several tutorials quite old in which you have seen different methods for displaying related posts in Blogger like the related posts widget with thumbnails and simple related posts with post titles only. This tutorial, however, will show you how to implement a really awesome Related Posts widget with thumbnails and posts snippets that will appear in the footer of all your blog posts.

If you want to get an idea of how it looks like, please visit this demo blog.

Now let's see how to add the related posts widget with thumbnails and summary in Blogger:

Adding Related Posts Widget with Snippets to Blogger Posts

Step 1. From your Blogger Dashboard, go to Template and click on Edit HTML

Step 2. Click anywhere inside the code area and then press CTRL + F to open the Blogger search box

Step 3. Type or paste this tag inside the search box and hit enter to find it:

</head>

After you found it, paste this script just above it:

<script type='text/javascript'>
//<![CDATA[
var relatedTitles = new Array();
var relatedUrls = new Array();
var relatedpSummary = new Array();
var relatedThumb = new Array();
var relatedTitlesNum = 0;
var relatedPostsNum = 4; // number of entries to be shown
var relatedmaxnum = 75; // the number of characters of summary
var relatednoimage = "https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjsM1ZEMyKQ5fW17DyaOQeBpeaaz8j7utrYdseQ58XMnW2wDYhlYQ6cZbhsMaNoO7SEaP67m0QEXA6vRacyh5PCWlrMKIHEkdWU3Yzi9tsqTGzUEfQODS7TZi2UzpS-tbeArpbuKR7tX80L/s1600/no_image.jpg"; // default picture for entries with no image
function readpostlabels(e){for(var t,r,l,a=0;a<e.feed.entry.length&&(t=e.feed.entry[a],a!=e.feed.entry.length);a++){relatedTitles[relatedTitlesNum]=t.title.$t,l="","content"in t?l=t.content.$t:"summary"in t&&(l=t.summary.$t),relatedpSummary[relatedTitlesNum]=removetags(l,relatedmaxnum),r="media$thumbnail"in t?t.media$thumbnail.url:relatednoimage,relatedThumb[relatedTitlesNum]=r;for(var d=0;d<t.link.length;d++)if("alternate"==t.link[d].rel){relatedUrls[relatedTitlesNum]=t.link[d].href;break}relatedTitlesNum++}}function showrelated(){for(var e=new Array(0),t=new Array(0),r=new Array(0),l=new Array(0),a=0;a<relatedUrls.length;a++)contains(e,relatedUrls[a])||(e.length+=1,e[e.length-1]=relatedUrls[a],t.length+=1,t[t.length-1]=relatedTitles[a],r.length+=1,r[r.length-1]=relatedpSummary[a],l.length+=1,l[l.length-1]=relatedThumb[a]);relatedTitles=t,relatedUrls=e,relatedpSummary=r,relatedThumb=l;for(var a=0;a<relatedTitles.length;a++){var d=Math.floor((relatedTitles.length-1)*Math.random()),n=relatedTitles[a],s=relatedUrls[a],m=relatedpSummary[a],i=relatedThumb[a];relatedTitles[a]=relatedTitles[d],relatedUrls[a]=relatedUrls[d],relatedpSummary[a]=relatedpSummary[d],relatedThumb[a]=relatedThumb[d],relatedTitles[d]=n,relatedUrls[d]=s,relatedpSummary[d]=m,relatedThumb[d]=i}for(var u,h=0,o=Math.floor((relatedTitles.length-1)*Math.random()),g=o,f=document.URL;h<relatedPostsNum&&(relatedUrls[o]==f||(u="<div class='relatedsumposts'>",u+="<a href='"+relatedUrls[o]+"' title='"+relatedTitles[o]+"'><img src='"+relatedThumb[o]+"' /></a>",u+="<h6><a href='"+relatedUrls[o]+"' target='_self'>"+relatedTitles[o]+"</a></h6>",u+="<p>"+relatedpSummary[o]+" ... </p>",u+="</div>",document.write(u),h++,h!=relatedPostsNum))&&(o<relatedTitles.length-1?o++:o=0,o!=g););}function removetags(e,t){for(var r=e.split("<"),l=0;l<r.length;l++)-1!=r[l].indexOf(">")&&(r[l]=r[l].substring(r[l].indexOf(">")+1,r[l].length));return r=r.join(""),r=r.substring(0,t-1)}function contains(e,t){for(var r=0;r<e.length;r++)if(e[r]==t)return!0;return!1}
//]]>
</script>

Note:
- To change the number of posts that are being displayed, modify the value in red (4)
- To change the number of characters to be shown in posts summary, modify the value in green (75)
- To change the default pic for posts with no images, add your URL instead of the one marked in blue
Step 4. Now that we added the script, we will need to add the CSS style. Just paste the following code above the same </head> tag:

<style>
.relatedsumposts {
padding: 0px 10px;
text-align: center;
/* width of the related posts area */
width: 120px;
float:left;margin-bottom:15px;
border-right: 1px dotted #E5E5E5;
display: inline-block;
}
.relatedsumposts h6 {
margin: 5px 0;
}
.relatedsumposts h6 a {
/* link properties */
color: #linkcolor;
text-transform: uppercase;
font-size:12px;
}
.relatedsumposts img {
/* thumbnail properties */
height: 82px;
width: 82px;
-webkit-border-radius: 50%;
-moz-border-radius: 50%;
border-radius: 50%;
}
.relatedsumposts p {
/* summary properties */
border-top: 1px dotted #E5E5E5;
border-bottom: 1px dotted #E5E5E5;
color: #summarycolor;
font-size: 10px;
height: 4em;
line-height: 1;
margin: 5px 0 0;
padding: 5px 0 15px 0;
}
#relatedpostssum {
width: 100%;
}
.relatedpoststitle {
font-size: 19px;
margin-bottom:15px;
}
</style>

Customizing the Related Posts Widget:

- Modify the value in red (120px) to adjust the width of the widget area
- Replace #linkcolor with the hex value of your color to change the color of post titles
- If you want to change the size of thumbnails, modify the values marked in violet (82px)
- To determine the border roundness, modify the values in orange (50%)
- To change the color of the post snippet, change #summarycolor with color hex value

Step 5. Next, search (CTRL + F) for the following code snippet:

<b:includable id='postQuickEdit' var='post'>

When you find it, click the sideways arrow to expand the code and scroll down until you find </b:includable> - see the screenshot for more help:



Step 6. Just ABOVE the </b:includable> tag, add the following html code:

<!-- Related Posts with Thumbnails Code Start-->
<b:if cond='data:blog.pageType == &quot;item&quot;'>
<b:loop values='data:post.labels' var='label'>
<b:if cond='data:label.isLast != &quot;true&quot;'>
</b:if>
<script expr:src='&quot;/feeds/posts/default/-/&quot; + data:label.name + &quot;?alt=json-in-script&amp;callback=readpostlabels&amp;max-results=50&quot;' type='text/javascript'/>
</b:loop>
  <div class='post-footer-line post-footer-line-4'>
   <div class='relatedpoststitle'>RELATED POSTS</div>
<div id='relatedpostssum'>
      <script type='text/javascript'>showrelated();</script>
    </div>
    <div style='clear:both;'/>
  </div>
</b:if>
<!-- Related Posts with Thumbnails Code End-->

Step 7. Click on the "Save Template" button to save the changes and you're done!

Note: in case you see the 'undefined' message, make sure that you have added the appropriate labels to your posts - which can be found in at least one more post, otherwise the script might not be able to find any related posts for that entry.

In the previous post I have mentioned that we will learn about how to create rounded images using CSS, without needing to edit them one by one using a program. Now that we have seen the basics of CSS, let's try to apply it on some pictures.

What we will do in this tutorial is to upload an image (HTML) and then add some rules in the stylesheet that will transform the outer shape to look like a circle... or, at least, to appear round. This will depend on the proportions of that picture we will use.

In fact, we can apply this effect to any picture, to a specific part of our blog or to all the pictures found in our blog. This depends on your tastes.

Marking up HTML

Obviously, the first thing we need to do in order to set a rounded border around an image is to get a picture and upload it to get the html structure. The code could be a little bit more complicated, but an image is built within the img tag, which basically, looks like this:

<img src="image_URL"/>

Screenshot:

Adding this code inside the HTML of the post with the url of our image - instead of the text in blue - we will be able to display it like this image on the left.

Usually, it might also contain an alt text, and sometimes, may have some predetermined dimensions (with a specific width and/or height). When we upload an image using the Blogger post editor, the code will also have a link pointing to the original image.

But if we want to modify this image using CSS, we need to add a class selector. We can add it in two ways: within the img tag or in a parent box. The name that I have chosen for the image selector is roundedcorners, however, you can add any name you want:

<img class="roundedcorners" src="image_URL"/>

<div class="roundedcorners">
<img src="image_URL"/>
</div>

Applying style to all homogeneous elements

But that selector alone won't do anything special. It needs to be linked to a style rule telling what to do with it. The same if when we add just classes, if these are not defined within the CSS, the appearance of a picture (or a certain element) will not change.

To change the shape of the all the pictures on our blog, this is what we should add to our CSS:

img {
border: 2px solid #BADA55;
margin: 0;
padding: 0;
border-radius: 1000px;
-moz-border-radius: 1000px;
}

And how this translates to your browser?

Search for images by name tag (img) and apply the following style:

• a solid green border of 2 pixels
• set the margins (space outside the border) and padding (space inside the border) to zero
• apply the rounded corner look to all the four corners

Now that we have this rule in our style sheet itself, we'll be able to see the picture as we want - take a look at the image on the right.

To declare a property correctly, we need to know what it does and how to write it - details which could be found all over the internet, although W3C is the authority in this.

For instance, the border-radius property initially requires four (4) values reading from left to right, which represent the roundness of the upper-left, upper-right, lower-right and lower-left corner. If you add a single value, it will make all the four corners to be equal with that value.

It is important to mention that when the value of the border exceeds the dimensions of the container, this border will create a circle.

How to apply the same style on the elements of the same container

Sometimes, we don't want all the images on our blog to be round, but only the ones that we choose, otherwise adding the style above within the head tag will make all the pictures taking this shape. Before, we used an HTML tag (img) and not a selector and, for this reason, the style will affect all our images.
To avoid this, we can do one of the things we saw at the beginning of this post and that was to place the image inside a div with the roundedcorners class. This way, only the images within the container with that class will be affected by the rule that will make them round.

<div class="roundedcorners"><img src="image_URL"/></div>

But the rule then should not affect the img tag directly, but the roundedcorners selector. In this case, you should write it like this:

.roundedcorners img {
border: 2px solid #BADA55;
....
}

This implies that this style applies only to images that are within the container with the roundedcorners class.

Final words

To end this tutorial on creating pictures with rounded borders, keep in mind that if these are not square, instead of becoming circular, they will look oval:

To fix this we should add the width and height with the same measure (value in pixels) to force the image cropping and to make it appear perfectly circular. That was all!

This tutorial will explain how to change the outside border of any image by using some simple CSS rules to make it round, but this is so easy doing this, that I'm finally going to make this post for other purposes.

The trick today that I'm going to publish in two parts is to help you to understand, at least, a little of what CSS (Cascading Style Sheets) is.

For those who would like to learn more, please take a look at this link and for those who really want to learn thoroughly, I recommend to visit this site.

Introduction and terminology

Style sheets aim to help sort out what is the structure of a website and which is its format or appearance. So, the CSS box model is, basically, a box that wraps around HTML elements, and determines how those boxes are presented in terms of colors, fonts, width, backgrounds etc.

The advantage is that, anytime we decide to change something, we don't have to change all the pages one by one, but simply, change the properties from the style sheet and these modifications will automatically apply in all the pages.

The style sheet is a set of rules made of selectors and declarations. The selector is to be used as a nickname or name of what you want to configure from the style sheet and apply to the HTML, and declarations are properties to which we add the desired values ​​(more information on CSS syntax)

Adding the CSS selector

If we add, for example, the code above in our style sheet, we might not see anything particular happening in our website. As I have mentioned above, the selector relates to the HTML and CSS so, if we want a box to take these values ​​for width, background color, border and font size, we need to include the selector within the HTML of a page element, like this:

<div class="SelectorName">Text here</div>

Here we added a rule telling the browser to interpret that this box has to be of a certain type or class. This class or selector could have some specific properties and values ​​defined in the style sheet, as you can see in the image above.

Now let's see how this will change the look of the box, while all others that don't have the SelectorName  name will follow the standard appearance.

Basically, when we add a rule in a style sheet, or modify an existing one, what happens is that all boxes marked with that selector will change their appearance according to the properties and values that we have defined in the style sheet.


Where to add the CSS style

This style can be added in external CSS files - create the CSS file with all the rules, upload it on a hosting site and get the URL of the file. To make use of it, include the following line in the header of your template. For Blogger, you can add it between <head> and <b:skin><![CDATA[/*:

<link href="syle.css" rel="stylesheet" type="text/css"/>

Note: replace the text in blue with the url of the CSS file.

You can also add the style directly in the HTML of the template by adding the CSS between the style tags:

<style>
.SelectorName {
background-color: #EAEAEA;
border: 1px solid #444444;
width: 200px;
font-size: 12px;
}
</style>

This can be added in the HTML of a page element as well. In this case, you don't need to add any selector to indicate where the CSS style is:

<div style="background-color: #EAEAEA; border: 1px solid #444444; width: 200px; font-size: 12px;">Text here</div>

In Blogger, the rules are between the <b:skin><![CDATA[/* and ]]></b:skin> skin tags. If we access the HTML of our template, we will find a bunch of codes in between these tags, which is actually the CSS styling that defines the appearance of our blog.

For those who don't want to touch the template code, we can add the CSS directly by going to the Blogger Template designer > Advanced > Add CSS.

That's enough for today. In the next tutorial we'll get to know how to add rounded corners to our images using CSS -> how to set a rounded borders around an image using CSS.

In this post, we'll talk about the 10 most common places in a site or blog where we can add AdSense ads and how we can implement these. Also, we'll get to know which are the most suitable formats based on those available in our AdSense account.

FAQ

Some questions that are likely to arise:

I can't find the codes, what should I do?
When searching for a specific code, make sure that you have no spaces before/after it. These are the default codes of Blogger and should be found in all the templates unless they have been modified by the template designer.

Why should I convert my AdSense code?
The Blogger's Template reads it as text and not as code so it is better to avoid any errors when trying to save it.

The ads are not displaying properly, why is that?
The ads could be affected by the styles (CSS) selectors (divs) containing them and some templates could be wrong designed, then you should consider modifying these styles, look for another relevant place or in extreme cases, change the template.

Can I put the all 10 codes on my blog?
No, you should choose just one of the locations where you want to put the ads considering that AdSense have some limits on the number of ads that could be displayed. Try to make a balance with your content.

Why there should be only 3 ads displayed on the main page?
This is due to the limit set by AdSense. Combine the type of ads (text, rich media ads and link units) if you want to show more ads.

Hopefully, this guide will be useful to those of you who need to display AdSense ads on your blog.

A few days ago, Mrpolie asked if there's a way to hide the author comments in the Recent Comments widget so that we would be able to see only readers' comments and our replies to be hidden. So, in this post I'll be sharing with you the Recent Comments widget that comes with this function. If you want to show just blog readers' comments rather than yours, you have just to change "Blogger User" text with the surname under which you are posting.

The main features of this recent comments widget:

- You'll be able to hide your comments
- Change the avatar size
- Set the number of comments to display
- Set the length of comment for the widget to display

Recent Comments Widget with Hide Author Function

Step 1. From your Blogger Dashboard, go to Layout and click on Add a Gadget link

Step 2. In the pop-up window, choose the HTML/JavaScript widget

Step 3. Copy-paste the following code:

Some changes before saving it.

- to set the number of comments to be shown, change the "5" value from the orange line
- for the number of characters, change the "67" (for the 2nd widget, it is 95) value from the green line
- to hide your comments, replace the Blogger User text TWICE with your username
- to change the size of avatar, change "50" from the blue line.
- if you don't want rounded avatars, delete this line:

-webkit-border-radius: 100px;-moz-border-radius: 100px;border-radius: 100px;

Step 4. Save your widget and you're done!

In this tutorial we will learn how to highlight the author comments so that they will have a different background color, border, or anything that makes them stand out from the others. To achieve this, we need to add a code in the Blogger's template and to modify the style according to our preferences.

  

How to highlight author comments in Blogger:

Step 1. Go to Template, click on Edit HTML

Step 2. Click anywhere inside the code area and try to find - using CTRL + F keys - this tag:

</body>

Screenshot:

Step 3. Just above it, paste the following code:

<script src='http://code.jquery.com/jquery-latest.js'/>
<script>
$(function() {
function highlight(){
$('.user.blog-author').closest('.comment-block')
.css('border', '1px solid #FFA500')
.css('background','#F1F1F2 url("http://www.blogblog.com/1kt/transparent/white80.png")')
.css('color', '#444444')
.css('font-size', '12px')
.css('padding', '10px');
}
$(document).bind('ready scroll click', highlight);
});
</script>

Customizing the Author Comments:

Border:
The line marked in orange represents the border's style.
What it can be done:

• 1px - you can increase the value to change the border's thickness
• solid - change the border's style to dotted, dashed, inset, outset etc.
• #FFA500 - this is the border's color value, change it with your own color

Background:
The line marked in blue represents the background's style. You can use a plain color or an image. By default there's a combination of both (a white transparent image with a gray plain color).
To change/add:

• a different color: replace the #F1F1F2 value with your own (use this tool to find the hex code of your desired color)
• an image: replace the defaul url http://www.blogblog.com/1kt/transparent/white80.png with that of your image

Font Color:
To change the font's color, replace the #444444 color value in green with your own. (you can use this tool to find the hex code of your desired color)

Font Size:
Modify the value in red by increasing/decreasing the "12" value in order to change the size of text.

Step 4. Now Save your Template.

To customize the entire style of threaded comments, please check my previous tutorial on How to Customize Comment's Background, Font Color and Border in Blogger.

The comments are an essential part of any blog as in them readers express their opinions about a post or a blog, thus it is important to spend a little of our time to make this part looking more stylish, accessible and neat.

To put our comments in order, we should make each comment easy to identify, so that we'll know from where it begins and to where it ends, otherwise it becomes a jumble of letters and our visitors could run away. Here are some methods to make some order by separating each comment.

- Add a Separator To Blogger Comments
- Add a Divider Below Comments in Blogger
- Fully Customize Your Blogger Comments By Changing The Background Color and Border

The first method is the easiest: we'll separate our comments by adding a border below each of them.

How to Add a Separator/Border To Blogger Comments

Step 1. To add a simple separator go to Template > Edit HTML and click on the small arrow on the left of <b:skin>...</b:skin>

Step 2. Click anywhere inside the code area and search using CTRL + F keys, for the following piece of code:

]]></b:skin>

Step 3. Paste the following style just above it:

- If we are using threaded comments (with the reply option):

.comment-block {
border-bottom: 1px solid #000000;
}
.comments .continue {
  border-top: 0px solid #000;
}

- If we are using previous commenting system (with no reply option)

#comments-block .comment-footer {
border-bottom:1px solid #000000;
}

Note: To change the border's color, replace the bolded color value and to change its thickness, increase/decrease the 1 value.

Step 4. Save the Template.

Instead of a simple border, we can also add a divider/image between our comments.

How to Add a Divider (Image) Between Each Comment in Blogger

Step 1. Go to Template > Edit HTML and search (CTRL + F) for the following piece of code:

]]></b:skin>

Screenshot:

Step 2. Paste the following just above it:

- If we are using threaded comments (with the reply option):

.comment-block {
background-image:url(https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgpm1FWhNog2ni8st17opaIEXtQ96ugOdsuB_8PjjFgf0GWWqwEne0VBXsKau71NSrIAxs5b6yMiJljC_2E4SWdmw9B1qudJ4X1R059A4j5-qHSNkLx8ebA5k2SGiKbmJnvEfoIl3tkmKDG/s1600/74.gif);
background-repeat:no-repeat;
background-position:center bottom;
padding-bottom:30px;
margin-top: -10px;
}
.comments .continue {
border-top: 0px solid #000;
}

- If we are using previous commenting system (with no reply function)

#comments-block .comment-footer {
background-image:url(https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgpm1FWhNog2ni8st17opaIEXtQ96ugOdsuB_8PjjFgf0GWWqwEne0VBXsKau71NSrIAxs5b6yMiJljC_2E4SWdmw9B1qudJ4X1R059A4j5-qHSNkLx8ebA5k2SGiKbmJnvEfoIl3tkmKDG/s1600/74.gif);
background-repeat:no-repeat;
background-position:center bottom;
height: 50px;
}

Note: The URL that is in blue represents the image that you can change as you like, just remember that at the height must set the height of an image with 30px more, for instance, if the image's height is 50px then the value will be 80px. This is for making sure that the image won't overlap the date of comments. (for threaded comments, increase/decrease the padding 30 value)

Step 3. Save the Template.

But you can still have more styles for each comment, for example adding a background color and a border.

How to Add A Border and A Background Color To Blogger Comments

Step 1. Go to Template > Edit HTML and search for the following piece of code:

]]></b:skin>

Step 2. Paste the following just above it:

- If we are using threaded comments (with the reply option):

.comment-block {
background:#F9F9F9; /* Background Color */
border: 1px solid #f1f1f1; /* Border style */
margin-bottom:20px;
-webkit-box-shadow: 0 1px 2px rgba(0, 0, 0, .4);
-moz-box-shadow: 0 1px 2px rgba(0, 0, 0, .4);
box-shadow: 0 1px 2px rgba(0, 0, 0, .4);
-moz-border-radius: 10px;
-webkit-border-radius: 10px;
border-radius: 10px;
}
.comments .comment-thread.inline-thread {
background-color: #FAFAFA; /* Background color behind the replies */
border-left: 4px dotted #E6E6E6; /* Border on the left side of replies */
}
.comment-content {
padding:2px 10px 10px 10px;
color:#444444; /* Font Color in Comments */
}
.datetime a {
font-style:italic;
font-size:9px;
margin-left: 2px;
}
.comments .comments-content .user a{
color:#1982D1; /* Author's name color */
font-size: 12px; /* Author's name size */
padding-left: 10px;
font-weight:bold;
text-decoration:none;
}
.comments .comment .comment-actions a,.comments .comment .continue a{
display:inline-block;
margin:0 0 10px 10px;
padding:0 15px;
color:#B4B4B7;
text-align:center;
text-decoration:none;
background:#F8F8FB;
border:1px solid #C2C2C5;
border-radius:4px;
height:20px;
line-height:20px;
font-weight:normal;
cursor:pointer;
}
.comments .continue {
border-top: 0px solid #000;
}
.comments .comments-content .icon.blog-author {
background-image: none;
margin-left: -10px;
}
.comments .avatar-image-container{
margin: 0px 0px 0px 0px;
padding: 0px 0px 0px 0px;
width: 40px;
max-height: 40px;
border: 1px solid #F2F2F2;
padding: 1px;
}
.comments .avatar-image-container img{
margin: 0px 0px 0px 0px;
padding: 0px 0px 0px 0px;
max-width: 40px;
height: 40px;
}

Step 3. Save the Template.

- If we are using previous commenting system (with no reply function):

Step 1. Search for this line in your template:

<b:loop values='data:post.comments' var='comment'>

Step 2. Then, add the following code just below of it:

<div class='comments-new'>

Step 3. Look a little further down and you'll see the </b:loop> code and just above it, add this:

</div>

Step 4. Now find this:

]]></b:skin>

Step 5. And just above of it, add this CSS code:

.comments-new{
background:#F9F9F9; /* Background Color */
border: 1px solid #f1f1f1; /* Bprder Style */
margin-bottom:20px;
-webkit-box-shadow: 0 1px 2px rgba(0, 0, 0, .4);
-moz-box-shadow: 0 1px 2px rgba(0, 0, 0, .4);
box-shadow: 0 1px 2px rgba(0, 0, 0, .4);
-moz-border-radius: 10px;
-webkit-border-radius: 10px;
border-radius: 10px;
}
.comment-body {
color:#444444; /* Font Color in Comments */
padding:10px;
}
.comments-new a {
padding-left: 5px; /* Link color */
color: #4A9BD8;
}
.comment-timestamp a {
font-style:italic;
font-size:9px;
padding-right:10px;
padding-left:10px;
}
.comments .avatar-image-container {
overflow: visible;
}

(The rounded edges will not work in Internet Explorer with CSS)

In either case, you can change the background color, border, etc.. in parts with annotations in green.

Step 6. Save the Template.

If you need more help, leave a comment below.

The Up and Down buttons can be used to navigate to the top and bottom of the page content, especially when on the main page are many articles or when an article has too many comments. These buttons have a fadeIn and fadeOut effect, this means that they will fade slightly when we are scrolling to the top or bottom of the page and additionally, have the function of going up/down the blog.

Demo

You can see a live demo on my blog, the buttons are located on the right side.

</body>

Step 6. And just above it, paste the code below:

<script src='http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js' type='text/javascript'/>

<div class='button_up' id='button_up' style='display:none;'/>
<div class='button_down' id='button_down' style='display:none;'/>

<script>
//<![CDATA[
(function(){var special=jQuery.event.special,uid1='D'+(+new Date()),uid2='D'+(+new Date()+1);special.scrollstart={setup:function(){var timer,handler=function(evt){var _self=this,_args=arguments;if(timer){clearTimeout(timer)}else{evt.type='scrollstart';jQuery.event.handle.apply(_self,_args)}timer=setTimeout(function(){timer=null},special.scrollstop.latency)};jQuery(this).bind('scroll',handler).data(uid1,handler)},teardown:function(){jQuery(this).unbind('scroll',jQuery(this).data(uid1))}};special.scrollstop={latency:300,setup:function(){var timer,handler=function(evt){var _self=this,_args=arguments;if(timer){clearTimeout(timer)}timer=setTimeout(function(){timer=null;evt.type='scrollstop';jQuery.event.handle.apply(_self,_args)},special.scrollstop.latency)};jQuery(this).bind('scroll',handler).data(uid2,handler)},teardown:function(){jQuery(this).unbind('scroll',jQuery(this).data(uid2))}}})();

$(function() {
var $elem = $('body');
$('#button_up').fadeIn('slow');
$('#button_down').fadeIn('slow');
$(window).bind('scrollstart', function(){
$('#button_up,#button_down').stop().animate({'opacity':'0.2'});
});
$(window).bind('scrollstop', function(){
$('#button_up,#button_down').stop().animate({'opacity':'1'});
});
$('#button_down').click(
function (e) {
$('html, body').animate({scrollTop: $elem.height()}, 800);
} );
$('#button_up').click(
function (e) {
$('html, body').animate({scrollTop: '0px'}, 800);
} );});
//]]>
</script>

Note: In case you want to remove the "Go to top" button, remove the 1st bolded code and to remove the "Go to bottom" button, remove the 2nd one.

Step 7. Finally, Save your changes by clicking on the Save template button. Enjoy!
