CSS tips

🎨

Embed small SVG icons, favicons, or background images directly in your CSS as data URLs to eliminate extra HTTP requests.

📏

Only embed images under ~5 KB as Base64. Larger images increase CSS file size significantly and are better served as separate files.

💡

Base64 images in CSS look like: background-image: url("data:image/svg+xml;base64,PHN2Zy4uLg=="). Paste your encoded output after the comma.

⚡

For SVGs specifically, URL-encoding the raw SVG source is often more compact than Base64 — compare both before choosing.
