If you're using Chrome, you have the option to perform an Audit on your webpage which will uncover any unused rules, along with their source file. Simply hit F12 to access the Developer Tools, navigate to "Audits," and click on "Run".
To access the Developer Tools, simply hit F12 on your keyboard and then navigate to 'Elements' in the top-left corner. Once there, click anywhere below the elements section and press Ctrl+F to open the find dialog box. Type in the term class and it will highlight all instances of this word used to define classes on the page with a yellow background. By clicking on these highlighted words, you can view the details of the class on the left side of the screen. Simply copy all of the classes to a notepad for reference.
Every modern web browser comes equipped with developer tools. These tools typically allow you to inspect elements by right-clicking on them. This feature enables you to view the specific stylesheets that dictate the appearance of each HTML element, complete with line numbers within the stylesheet. For example, Opera has an extension called Dust-Me Selectors (available at ) that can identify and remove unused CSS selectors. Similarly, there are likely other plugins or extensions available for different browsers that offer similar functionality.
