There are several ways to find unused CSS in a web page. One way is to use the developer tools in your web browser. For example, in Google Chrome, you can open the developer tools by pressing `Ctrl+Shift+I` (Windows) or `Cmd+Opt+I` (Mac). Then, go to the "Audits" tab and click "Run audits". Make sure that "Web Page Performance" is checked. This will list all the unused CSS tags on the page .
Another way to find unused CSS is to use a tool like Unused CSS Finder by Jitbit . This free tool crawls your website for unused CSS selectors. It follows internal links on your website recursively and looks on multiple pages. The tool extracts stylesheets found in all linked CSS files and inline styles, parses the page to find unused selectors, and shows unused selectors allowing you to remove unused CSS from your stylesheets .
It's important to note that removing unused CSS can help improve the performance of your website by reducing the amount of data that needs to be downloaded by the browser. This can result in faster page load times and a better user experience.
