CSS Explainer (AI)
CSSPaste any CSS and get a plain-English breakdown of every selector and property: powered by GPT-4o mini
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 GPT-4o mini 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 OpenAI's API for processing, avoid pasting anything proprietary or sensitive if that's a concern for your project.
