So did you have to dig into Chrome's cache, or did you just view source on the stylesheets?

The chrome cache on my desktop has a different version of the .css file to the one on my laptop. I know next to nothing about web page coding and even less about mucking about with the cache so my chances of ever substituting the old file for the new are slight.

Open developer tools/inspector and click somewhere on the page, or an element in the html (<div>, <p> or whatever). Under "rules" it will tell you from which file it is pulling the styles for the selected dom element.

I found what I needed using about:cache, extracted the file with chromecacheview, copied the text by opening it in Chrome and finally pasted the text into Stylebot as a new CSS to get my old view of the site back.

Little things please little minds.

Your second response is exactly what I was asking for.

Well, I got there in the end.
