CSS Specificity Calculator Online - Calculate CSS Selector priority for free

The CSS Specificity Calculator tool helps you calculate and compare the specificity of CSS selectors. Understanding specificity is key to debugging CSS conflicts and writing effective CSS. The tool parses the selector into four components: Inline styles (top), IDs (#id), Classes/Attributes/Pseudo-classes (.class, [attr], :hover), and Elements/Pseudo-elements (div, ::before). Enter multiple selectors at once to compare and sort from high to low. Especially useful when debugging why a CSS rule is not being applied, or when needing to override styles without using !important.
