Readme
Add Selector Specificity to your project:
npm install @csstools/selector-specificity --save-dev
import parser from 'postcss-selector-parser';
import { selectorSpecificity } from '@csstools/selector-specificity';
const selectorAST = parser().astSync('#foo:has(> .foo)');
const specificity = selectorSpecificity(selectorAST);
console.log(specificity.a); // 1
console.log(specificity.b); // 1
console.log(specificity.c); // 0
selectorSpecificity
takes a single selector, not a list of selectors (not : a, b, c
).
To compare or otherwise manipulate lists of selectors you need to call selectorSpecificity
on each part.
The package exports a utility function to compare two specificities.
import { selectorSpecificity, compare } from '@csstools/selector-specificity';
const s1 = selectorSpecificity(ast1);
const s2 = selectorSpecificity(ast2);
compare(s1, s2); // -1 | 0 | 1
s1 < s2
then compare(s1, s2)
returns a negative number (< 0
)s1 > s2
then compare(s1, s2)
returns a positive number (> 0
)s1 === s2
then compare(s1, s2)
returns zero (=== 0
)For CSSTools we always use postcss-selector-parser
and want to calculate specificity from this AST.
