How To Remove Unused CSS in WordPress

There are several ways to remove unused CSS in a WordPress website:

1. Use a plugin: There are several WordPress plugins available that can scan your website and identify unused CSS, such as Autoptimize, WP Clean Up, and Clearfy.
2. Use online tools: There are online tools such as UnusedCSS.com and PurifyCSS.com that can scan your website and generate a list of unused CSS styles.
3. Manually check for unused styles: You can manually check for unused styles by using browser developer tools to inspect the CSS styles being applied to each element on your website.
4. Use CSS preprocessors: CSS preprocessors like Sass and Less allow you to use variables and functions to organize your CSS, making it easier to identify and remove unused styles.
5. Use modern CSS methodologies like BEM, SMACSS, and ITCSS.

It is important to keep in mind that removing unused CSS can increase page load speed, but it is also important to keep the code maintainable.
