CSS & color tools

CSS playground (shadow, gradient, clip-path, button), color convert with OKLCH, and WCAG contrast.

• CSS Playground — Generate box-shadow, gradient, radius, flex, clip-path and button CSS locally in LocalKit. Preview without uploading.
• Color Converter — Convert HEX, RGB, HSL and OKLCH with a local palette in LocalKit. Color math stays in your browser—no upload.
• Contrast Checker — Check WCAG contrast ratios between two colors in LocalKit. Validate accessibility locally in your browser—values stay on-device with nothing uploaded.

All listed tools run in your browser. LocalKit does not upload content for computation.
