CSS Validator Online — Because Your Styles Deserve a Reality Check 🎨🔍

Source: Dev.to

🧪 What the CSS Validator Does for You

• Paste, upload, or link to a CSS file and run validation.
• Checks syntax, property names and values, braces/brackets, selectors—everything that can go wrong in CSS.
• Flags invalid or deprecated properties and warns about compatibility issues.
• Helps you spot missing semicolons, mismatched braces, typos, or bad rules—basically all the little mistakes that make browsers throw tantrums.
• Works entirely in your browser—no data leaks, no server uploads, just quick, local checking.

✅ When & Why You Should Use CSS Validator

• Building websites or web apps – Validate before deploying or committing to catch typos, misspelled properties, or invalid rules that could break layouts across browsers.
• Working on legacy / copy‑pasted styles – Clean up messy CSS from old projects, WYSIWYG editors, or tutorials and standardize your styles.
• Ensuring cross‑browser consistency – Valid CSS minimizes rendering quirks and layout differences in Chrome, Firefox, Safari, etc.
• Optimizing for performance & maintainability – Cleaner, valid CSS is easier to debug, review, and maintain, with fewer hacks and redundancies.
• Learning & enforcing good practices – Provides immediate feedback for newcomers, helping them learn correct syntax and proper stylesheet structure.
