Funny you should say that!
The mention of Stylus jogged my memory that I was already doing exactly that on 360Chrome, and have been doing so for well over a year!
Strangely though, if I switch off Stylus now the Digital Spy forum site still looks OK, so they've obviously changed something.
I've tried installing Stylus on Thorium, and importing the Stylus settings from 360Chrome, but it doesn't work, the font is still wrong.
I've attached my Stylus settings file, do you think it's still correct?
The site still looks correct in Supermium without Stylus even installed.
