Cascading Style Sheets — page styling rules.

What is text/css?

text/css is the media type for CSS stylesheets served as external <link rel="stylesheet">. Browsers will refuse to apply a stylesheet if the server declares any other type — a common misconfiguration.

Typical usage

External stylesheets linked from HTML pages.

Common gotchas

Serving .css files as application/octet-stream (a common misconfiguration on static hosts) causes browsers to silently skip the stylesheet.
