Checking for unused CSS classes on a page
css
Solution
In Chrome, you can Audit your page and this will reveal unused rules, including which file they come from. Just press F12 to load up the Developer Tools, click on "Audits," and then "Run".
Problem
I am trying to streamline my page. Currently I have several CSS files included. I would like to eliminate some CSS includes by getting just a few styles that are used from one large CSS file. What is the best way to figure out which styles are used from a particular CSS file?
