CSS Validator

CSS Validator is a tool that checks Cascading Style Sheets (CSS) code for syntax errors, compliance with CSS specifications, and potential issues. It parses CSS documents and reports on errors, warnings, and best practices to ensure code quality and cross-browser compatibility. This helps developers create standards-compliant and efficient stylesheets for web applications.
