CSS that
talks back.

Your stylesheets just got a voice. Ask anything — specificity, layout, accessibility, performance — and get answers grounded in the code you actually wrote.

No spam. One quiet email when we open the doors.

Debug like you have a senior next to you.

Paste a snippet. Describe the bug in plain English. Get an answer that names the rule, the cascade, and the fix — with citations to the spec.

Refactor with the cascade on your side.

Convert legacy stylesheets to nesting, layers, and logical properties. Trim dead rules. Promote magic numbers to tokens. Without breaking anything.

Learn the why, not just the fix.

Every answer comes with the reasoning — specificity math, box-model trade-offs, browser quirks. You walk away knowing more than when you started.

Not a chatbot.

A CSS collaborator.

css.chat reads your stylesheets, understands your design tokens, and speaks fluent specificity. It knows the difference between :where() and :is(). It knows why your position: sticky isn’t sticking. It knows that flex: 1 isn’t the same as flex: 1 1 0 and it’ll tell you why that matters today.
