What is normalize-selector?
The normalize-selector npm package is designed to normalize CSS selectors by formatting them into a consistent structure. This can be particularly useful for CSS processing tasks, such as minification, linting, or when implementing CSS-in-JS solutions where consistent selector formatting is crucial. It helps in cleaning up and standardizing selectors by removing unnecessary whitespace, sorting pseudo-classes, and ensuring a uniform structure.
What are normalize-selector's main functionalities?

"const normalize = require('normalize-selector');
const normalizedSelector = normalize(' ul > li:first-child ');
console.log(normalizedSelector); // Outputs: 'ul > li:first-child'"
