Identifying posts/pages that use specific css class



The Posts List (or Pages List) admin page has a search. If the custom class is in the content, it will find it.
You can also use a plugin like Search Regex.

1300 lines seems excessive. Perhaps instead of moving the definitions into the posts themselves, you can combine or generalize to pare down the rules. Surely some of these should be defaults in your theme CSS? It’s better to have CSS in one place than to have it spread haphazardly among the posts.

Thanks Joy.I went back and tried the post search again. This time it worked! The problem was that I was searching for the css class with a leading dot “.min-width-200” – which returned no results. When I search for “min-width-200” then it correctly identifies the posts that use it.

The reason I have so many lines of css is because in my blog I like playing with layout (graphic design), so I often experiment with custom css. Here in the UK I get page load speeds of under 1 second, so performance isn’t taking a hit. It’s more an issue of editing such a long css file.

I appreciate your thoughts about keeping css all in one place but the alternative argument is that it is bad practice to load unused css on every page. I use a plugin “simple css” which provides a meta box under each post for post-specific css. This gets rolled into one css file on the backend so does not increase the number of files required to load the page. I guess the downside is that the css can’t be cached by the browser effectively if it keeps changing from page to page. The balance, for me I think, is to offload css that is only used on one or two posts, so I can trim down the main custom css to theme specific styling that is used on every page.
