Minimizing HTTP Requests

Reduce the number of HTTP requests for CSS files by combining multiple stylesheets into one or using CSS sprites.

Using CSS Sprites

Combine multiple images into a single sprite image and use CSS to display specific portions, reducing HTTP requests.

Host CSS files on content delivery networks (CDNs) to improve loading speed for users in different geographical locations.

Leveraging Browser Caching

Set appropriate cache headers and expiration times for CSS files to leverage browser caching and reduce repeated downloads.
