About W3C CSS Validation Service
The W3C CSS Validation Service checks Cascading Style Sheets, on their own or inside (X)HTML documents. You can validate by URL, by uploading a file or by pasting CSS directly.
Options let you choose a profile such as CSS level 1, 2, 2.1, 3 or CSS 3 with SVG, a target medium such as screen or print, how many warnings to show and how vendor extensions are treated. A download page is also provided for running the validator yourself.
