About this tool
Calculate CSS selector specificity scores in real time to debug cascade conflicts and override issues. Useful for frontend refactoring, design system consistency checks, and stylesheet maintenance when multiple selectors compete for the same element styles.
Frequently Asked Questions
What format is used for specificity?
The tool outputs specificity as a,b,c where a is IDs, b is classes/attributes/pseudo-classes, and c is element selectors.
Can I check multiple selectors at once?
Yes. Paste one selector per line and each gets an individual score.
Does higher specificity always win?
Higher specificity generally wins, but !important and source order can also affect final style resolution.
