Frequently Asked Questions

A CSS sprite is a single image file containing multiple smaller images arranged in a grid. Each image is shown individually in HTML using CSS background-position to clip the relevant section.

Sprites reduce HTTP requests. Instead of loading 20 separate icon images, one sprite loads once. This improves page load speed, especially on mobile connections.

Set the sprite image as a background-image, then use background-position and background-size to show the specific icon for each element.

Less critical than before, since HTTP/2 handles multiple requests efficiently. But sprites still reduce bandwidth and provide exact pixel control over icon display.
