Kudos to Adam Karas for making the only comprehensible guide I could find on how to style DISQUS with CSS.
Karas makes this very easy, but I thought I would add a note for anyone using DIY Theme’s Thesis framework. Thesis will jive with this very easily, so long as you paste the header code into the “Header Scripts” box on the Thesis Options page under Appearance in the WordPress backend. Then, simply create a disqus-form.css file in the Custom folder where your custom.css and custom-functions.php file reside.
You’re done!
