Sometimes the simplest things really give me a kick. I use classes almost exclusively instead of styles. My CSS is a long list of classes in the main consisting of the first letter of each word in every which kind of style definition. In this way I can quickly hop and chop from this to that. I got stumped on how to use calibre's 'find' for any kind of class name consisting of one or more letters. It got lost due to being surrounded by spaces, other classes, or quotation marks. So I asked AI and it gave me: class="[^"]*X[^"]*"
I remove X and put in whatever I am looking for, then make sure the search says 'regex' instead of 'fuzzy.' I also put it in 'saved searches' in case I forget.
