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 JavaScript quiz generator for difficulty-based beginner practice, move into the Coding Quiz for Kids to practice HTML, CSS, and JavaScript basics, jump into 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. When you want to understand layout systems, the CSS flexbox playground lets you test direction, alignment, wrapping, and item sizing visually, while the CSS grid playground adds rows, columns, draggable placement, and span controls for two-dimensional layouts.
