CSS.GG

An open-source icon library that delivers over 700 pure CSS, SVG, and Figma UI icons alongside 6000-plus glyphs, patterns, colours, and layout utilities for web developers and interface designers. The project stands out for rendering icons entirely through CSS rather than image files, which brings advantages in scalability, customisability, and load performance — no sprite sheets, no font files, no JavaScript dependencies. Developers integrate an icon by adding a CSS class to an HTML element, keeping the markup clean and the bundle small. Beyond the pure CSS approach, the same icon set is also available as SVG files and as a Figma library, so designers can work with the icons in their preferred tool before handing off to development. The Figma community integration is particularly active, letting designers tweak stroke width, colour, and size directly in the design file. The GitHub repository has attracted significant community traction with thousands of stars, and the maintainer publishes regular updates adding new icon categories and refining existing ones. The collection covers the common UI surface — navigation arrows, media controls, form inputs, social brand marks, software tools, and miscellaneous interface glyphs — plus decorative patterns, colour palettes, and layout helpers that extend its usefulness past simple iconography. Because everything is CSS or SVG, icons inherit the parent element's colour and scale without quality loss, making them ideal for responsive and theme-aware interfaces. The library is suitable for front-end developers and UI designers who want a lightweight, hackable icon system without the overhead of icon font libraries or raster sprite packs.
