CSS Sprites refer to combining multiple images into one large image and using CSS background-position to display the correct image.

With a single request, you can display different images, which helps reduce the number of HTTP requests.

2. Minimize HTTP Requests

Every time your website requests assets like images, CSS, and JavaScript files from the server, it creates an HTTP request.

To reduce the number of HTTP requests, consider minimizing the number of assets your website requires.

3. Caching

Caching works by storing frequently requested items like images, CSS, and JavaScript files on the user’s browser or using a CDN (Content Delivery Network).

With caching, the browser can quickly retrieve previously requested files without sending another HTTP request to the server.

4. Concatenation

Concatenation is the process of combining multiple CSS and JavaScript files into a single file. With concatenation, the number of HTTP requests is reduced since only one file is requested from the server.

5. Using HTTP/2

HTTP/2 provides numerous performance optimizations that can help reduce the number of HTTP requests by using server push, multiplexing, and header compression.

So, reducing the number of HTTP requests made to the server can help improve backend performance. By using CSS sprites, minimizing HTTP requests, caching, concatenation, and HTTP/2, you can improve website performance and user experience.
