How to customise comments template?

I need help. My comments are all messy. I want to put people's comments in boxes and the box where they type to enter their comments like this site:
http://skins.b2evolution.net/a.php?title=title&more=1&c=1&tb=1&pb=1#comments

At the moment, mine looks like this:

I'm not sure where to edit it.

Try adding this to the very beginning of your custom.css file:

@import url(../../rsc/forms.css);

It looks a bit better now after adding the code. But do you know how I can put a box around each comment?

You could add this to the end of your stylesheet:

.bComment {
border: 1px solid #000;
}

And play around with the values. Add margins and padding if you want, too.

Thanks :D!
