How to find all files using a specific .CSS file
I wanted to get rid of a certain .css file, it seems i do not have any files using it currently, but I want to ensure that is the case. Is there a way to find all files associated to a certain css file?
On a similar note, I'd really like to be able to find all external links pointing to a particular page. For the same reason, if I remove a page, I want to be positive that there are no links to that page on any other pages on my website.
I think this is a pretty basic thing so hopefully someone can help me and make me feel silly that I didn't know how to do that!
Thank you in advance for your help
