CSS Specificity Calculator - Calculate Specificity

Calculate CSS specificity online for free. Find selector weight and priority. Debug CSS conflicts.

CSS Specificity Calculator

Calculate CSS selector specificity to debug styling conflicts

CSS Selector

Example Selectors

How CSS Specificity Works:

IDs (#id) have the highest weight (100 points each)
Classes (.class), attributes ([attr]), pseudo-classes (:hover) have medium weight (10 points each)
Elements (div, p) and pseudo-elements (::before) have the lowest weight (1 point each)
Higher specificity wins when multiple rules target the same element
If specificity is equal, the last rule in CSS wins

Frequently Asked Questions

How is specificity calculated?

IDs count as 100, classes/attributes/pseudo-classes as 10, and elements/pseudo-elements as 1.

What wins if specificity is equal?

The last rule in CSS wins when specificity is identical.

Does !important affect specificity?

!important overrides all specificity, but it is not considered part of the specificity calculation.

What about inline styles?

Inline styles have higher specificity (1,0,0,0) than any selector, except !important.
