Frequently Asked Questions

Why should I use CSS sprites?

CSS sprites are a classic performance technique. They reduce the number of HTTP requests, which is especially beneficial on slower connections or sites with many small assets like icons or UI elements.

Which layout should I choose?

Vertical and horizontal layouts are easiest to debug. Grid layout is the most efficient for minimizing the final image area and file size.

What about high-DPI (Retina) screens?

You can generate a sprite sheet with double-sized icons and use "background-size" in your CSS to scale it down for sharp rendering on high-DPI displays.
