CSSPaste any CSS and get a plain-English breakdown of every selector and property: powered by Claude
About CSS Explainer (AI)
Inheriting a stylesheet full of selectors like `:not(.active):nth-child(2n+1)` from a library or a coworker's PR is a common onboarding friction point, and this pastes into Claude on the server to get a plain-English breakdown of every selector and property, which is faster than reverse-engineering it from a spec. It's built to explain what CSS does, not to audit it: for bugs or browser-compatibility issues, your browser's dev tools or a linter is the right tool instead. It works best on plain CSS; preprocessor-specific syntax like Sass mixins or variables gets explained more loosely than precisely. Since your pasted CSS is sent to Anthropic's API (Claude, with OpenAI as a fallback) for processing, avoid pasting anything proprietary or sensitive if that's a concern for your project.
