# W3.CSS

Unclassified · [Official website](https://www.w3schools.com/w3css/)

W3.CSS is a free CSS framework from W3Schools for building responsive web pages with ready-made classes for layout, colours, typography and components. It is a single stylesheet with no JavaScript library required. If the stylesheet is loaded from the W3Schools server instead of the site's own server, each page view makes the visitor's browser contact W3Schools.
