Comments-page has no background but text

Hi!
When someone comments on my homepage, https://still-around.com, they come to a page called, https://still-around.com/index.php/?p=11#comments. That page contains all the text supposed to be there but no background what so ever. How can I change this? I bet it’s just to add a text-line somewhere but I don’t know where somewhere is!

Please e-mail me your answers, or comment on my homepage, converseprincess[a]gmail.com
