For those who would like to know more about HTML and CSS, in this post we will learn the differences between margin and padding CSS properties that are used to add space between the HTML elements, thus preventing the elements from getting 'stuck' together.
Although both have similar functions, each work in a different way.
Just as you have the option to define the borders for each side of your HTML elements (eg. borders for the sidebar), you can do the same with the margin and padding properties. All you need to to do is to change the top, right, bottom and left values.
The values that you can use include: pixels (px), centimeters (cm), millimeters (mm). em units (em), x-height (ex), inches (in), picas (pc) and point sizes (pt).
When using margin and padding, you need to add a value for each 4 corners of an element, as follows: top, right, bottom, left. Each value must refer to the each side of the HTML element. The first value is for the top, and they follow a clockwise direction, so the value would be close to the right, then bottom, and finally, left.
Example 1:
Example 2:
padding: 5px (top and bottom) 15px (left and right);
margin: 10px (top and bottom) 5px (left and right);
If it helps you visually, think of an A4 page of type inside a picture frame. The margin is the space between the edge of the sheet of paper and the other elements (the parts of the frame), while the padding would be the space between the edge of the sheet and where the type starts on the page. The border would be the edge of the sheet of paper.
It's probably easier to understand if you have borders, then it also becomes obvious which one to use. Do you want "space" after the border (outside the element = margin) or before the border (inside the element = padding).
Although both have similar functions, each work in a different way.
- Padding determines the inner margins, being used for changing the distance between the content of a given element and its border.
- Margin is the space outside of an element affecting how far the element is away from other elements.
