Tip
Always end every declaration with a semicolon to prevent unexpected parsing errors in your stylesheet.
Did You Know?
Invalid CSS properties are silently ignored by browsers, which often leads to layout inconsistencies.
Best Practice
Validate your CSS before minifying it to ensure no syntax errors are locked into your production code.
Q: Does this validator support CSS3? A: Yes, it is fully compatible with modern CSS3 syntax, including animations, transforms, and grid layouts.
Q: Why is my CSS not applying despite passing validation? A: Validation checks for syntax errors, but issues like specificity conflicts or incorrect file paths can still prevent styles from rendering.
Q: Can it detect unused CSS selectors? A: This tool focuses on syntax and structural errors rather than identifying unused or redundant CSS rules.
Q: How do I fix a 'Missing semicolon' error? A: Locate the line indicated in the error report and ensure the property-value pair before it ends with a semicolon (;).
Tip
Use the line numbers in our validator to quickly jump to specific errors in large CSS files.
