Gridpaint

Gridpaint turns the fiddly parts of CSS into something you build by eye and copy straight into your project. Instead of guessing at grid-template values or hand-tuning gradient stops, you set it up visually, watch the result update live, and get clean, correct CSS ready to paste — no memorizing syntax required.

The grid builder lets you define rows and columns with real units — fixed pixels, flexible fr, auto, percentages, min/max — set gaps, and see the layout render instantly as a live preview. Adjust track counts and sizes, place items across cells, and Gridpaint writes the exact grid-template-columns, grid-template-rows, and gap declarations for you, formatted and ready. The gradient studio does the same for color: pick a linear or radial gradient, add and drag as many color stops as you like, tune angle and position, and copy the precise gradient string. On top of the two core tools sit more visual generators — box-shadow, border-radius, and transforms — each with live preview and instant code, so the app grows into a whole visual CSS toolkit.

Everything is built for real use: a live preview beside every tool, one-tap copy of the generated code, a saved library of your favorite grids and gradients to reuse later, and a clean layout that keeps the controls, the preview, and the code all in view. It's the CSS you'd write, without the trial and error.

Everything runs on your device: no account, no connection, no ads. Just set it up, see it, and copy the code.
