What is a CSS property extractor?
It is a tool that reads CSS code, ignores the class names, ID selectors, and values, and outputs only the declarative properties (like color, padding, display).
CSS Property Extractor is a specialized parsing tool that scans your CSS code to extract a list of all used property declarations. Whether you are auditing a massive legacy codebase to find obsolete properties (like `float`), isolating layout properties for a component library, or simply studying the CSS architecture of a framework, this tool isolates the keys (e.g., `font-size`) from the values for instant analysis.
The extractor works by dividing the CSS into rulesets, parsing the content inside the curly brackets `{...}`, and splitting each declaration at the colon `:`. It then captures and cleans the property name (the left side), ignoring the values, selectors, and comments. This all happens instantly in your browser.
