CSS Combo Builder
Stack gradient, shadow, border radius, and glass blur into one component, then use Chaos Mode to expose overflow, contrast, RTL, text-scaling, and focus risks before you ship.
.my-element
.my-element {
background: linear-gradient(135deg, #4f46e5 0%, #ec4899 100%);
box-shadow: 0px 18px 40px -12px rgba(79, 70, 229, 0.45);
border-radius: 28px 28px 28px 28px;
border: 1px solid rgba(255, 255, 255, 0.35);

Chaos Mode
Will this CSS survive the real world?
Six hostile-context previews run entirely in your browser. Results are best-effort signals, not a replacement for testing in your product.

Optional hardening patch
Copy this separately when you want safer wrapping, visible keyboard focus, forced-colors support, and reduced motion. It does not change the main export.

Frequently asked questions
Why is this different from a single-property generator?
Instead of copying five separate snippets from five different tools, you get one finished, ready-to-paste component combining all the effects together.
Can I export for Tailwind or styled-components?
Yes — use the export format tabs above the code block to switch between raw CSS, Tailwind arbitrary values, and a styled-components snippet.
What does the Chaos Mode score measure?
It combines browser-measured overflow checks in six hostile contexts with a WCAG contrast estimate for both gradient endpoints, plus focus and motion readiness checks. Treat it as an early warning system, then test the component in your real interface.
Does the hardening patch change my generated CSS?
No. It is a separate, optional snippet you can copy when you want safer text wrapping, keyboard focus, forced-colors support, and reduced-motion behavior.
