CSS Specificity Calculator Online
A CSS specificity calculator turns any stylesheet selector into a precise three-part score showing exactly how many IDs, classes, and elements it contains.
UI engineers often hit a wall when a seemingly perfect style rule gets silently ignored by the browser. Manually counting nested IDs and pseudo-classes across fifty lines of legacy code is how mistakes happen, but our CSS Specificity Calculator breaks down the math visually so you know exactly which rule wins.
How to Use the CSS Specificity Calculator
- Provide the CSS: Paste a single selector, drop in a full stylesheet, or upload a .css file.
- Review the score: Read the red, blue, and green bars to see the exact count of IDs, classes, and elements.
- Find the winner: Check the sorted list or use the comparison mode to see which rule overrides the rest.
