CSS Basics: The Box Model
If you’ve been using CSS for a while, then this post will probably teach you nothing new. I just wanted to state the obvious even if I’m the only one who benefits from it.
While I was (re-)learning CSS, I came across these two properties called margin and padding. At first, they seem to be doing the same thing namely providing space between HTML elements. But although they seem to fulfill the same purpose, there’s a clear distinction between the two.
The margin is intended for providing space between outside HTML elements or the sides of the page. Padding is used for providing visual space between the content and the border of the box.
The first example provides a margin to add visual space between the border and the parent element. The second one provides space between the border and the content.
I agree that this is trivial, but it matters to understand the difference between these two properties when using CSS.
