Do you remember that time when EVERYTHING changed...?

Any chance of an idiot's guide for this? I have added minimalist in Chrome, where do I copy and paste the code to?

Sure!

1. Click Minimalist button in top left of Chrome.
   
2. Click Dashboard button.
   
3. Click "Data".
   
4. Paste above code into the Import/Export panel.
   
5. Click Import.
   
   

That should create a "module" called "LFGSS Styled" which you can turn on in Minimalist (it might turn on by default, I can't remember) and then when you refresh the LFGSS site the style changes will be applied.

You can edit the module to have a look at the style changes and change the font yourself, if you looooove CSS.
