HTML and CSS Reference
In-Depth Information
URIs
A URI value (
<uri>
) is a reference to a file such as a graphic or another style sheet. CSS
defines a URI as relative to the style sheet that contains it. URI stands for Uniform Resource
Identifier, which is the more recent name for URLs. (Technically, URLs are a subset of URIs.)
In CSS, which was first defined when URIs were still called URLs, this means that references
to URIs will actually appear in the form
url(<uri>)
. Fun!
