Free Playground Tools
Learn by editing live code, not static screenshots.
Zap Code tools are small, fast playgrounds for testing real front-end ideas. Start with the HTML color picker to explore HEX, RGB, HSL, palettes, and contrast, or open the CSS animation playground to experiment with timing, keyframes, transforms, and copy-ready code in one screen.
