Thanks for your answer, but the above code is just an example, I don't want to change only blockquotes. I want to create a list of all classes and ID's to which roboto is assigned. With a script running through a large CSS file, outputting a list of all classes that I can then use in my child-theme to change roboto in all instances where the main theme has set it.

I am using a WordPress premium theme that has a 25.000+ lines styles.css. I want to change the font and main color sitewide, and for this I would like to catch ALL classes and IDs that use them for my childtheme. Manually searching through 25.000 lines and then selecting and copying the classes together is a very slow procedure, and I am sure this can be automated with RegEx, but I only know that it exists but not how it works, especially not for such a vast function. But at least I could figure out the logic that a script for such a task would need to follow. So let's say I need a rule that collects ALL classes to which Roboto is assigned. Basically it needs to 1. find Roboto, then 2. go back to the { and 3. collect everything before { until 4. the last } before, so it needs to go backwards searching 5. Then it needs to add a comma to the last entry, so the list can continue. The result will be a very big list of comma-separated classes which I can then easily assign the new font to. Can someone figure out such a RegEx String, or better to say, write such a php script? ... ... last CSS rule ending here. } .td-page-content blockquote p, .td-post-content blockquote p, .wpb_text_column blockquote p, .td_block_text_with_title blockquote p, .bbpress blockquote p, .woocommerce #tab-description blockquote p, .mce-content-body blockquote p, .comment-content blockquote p { font-family: 'Roboto', sans-serif; font-size: 32px; line-height: 40px; font-weight: 400; font-style: italic; text-align: center; text-transform: uppercase; color: ... ... ... ...
