Question

We had a designer do our html/css and while updating some code I noticed this:

img tags just reference the path to the image:

<img src="/images/pic.png">

But for css (with the background tag), it’s specified using a url:

header { height: 73px; background: url(/assets/maudi/nav.png); }

What is the importance of url?

Answer 1

HTML doesn’t have anywhere that can accept “a URL or something else”.

CSS does. The background property being a prime example.

background: blue;

Is blue a color or a relative URL?
