XF 2.2 How do I make my forum list font sizes look like it is here?

[Spartan]

there is too much empty space on my forum list page. I'd like it to look like it is here on xenforo. I'd also like to increase the font size in a thread without affecting the font sizes elsewhere.

To increase font size in thread, put the following code in extra.less:

Thread font size:

.message-body {font-size: 20px;}

Quote font size:

.bbCodeBlock.bbCodeBlock--quote .bbCodeBlock-content {font-size: 20px;}
