About W3.CSS

webatla tracks 45,849 live websites using W3.CSS, 0.0% of every site we index. Download the full list of websites that use W3.CSS as a daily JSONL export. Every record includes the domain plus DNS, WHOIS, IP address, hosting country and global rank.

W3.CSS is a free, modern CSS framework developed by W3Schools that emphasizes simplicity, speed, and responsiveness. Unlike many CSS frameworks, W3.CSS has no JavaScript dependencies and is designed to be smaller and faster than alternatives such as Bootstrap, making it suitable for lightweight web projects.

W3.CSS provides a responsive grid system, pre-styled UI components including cards, modals, tabs, accordions, and navigation bars, along with a color palette and animation utilities. It is particularly popular among beginners and developers learning web design through W3Schools tutorials. The framework is entirely free to use with no licensing restrictions and requires no installation beyond including a single CSS file.
