Custom CSS?

Is it possible to do this, if the version of my forum is phhpbb2?

Are you asking if it's possible to customize the look of your forum using the CSS style sheet? Yes . . . .

Further, phpbb2 allows the ability to purchase template editing. I'm not at all familiar with the particulars, but look in your admin panel: Display > Templates (look on the bottom left)

Hope this helps!

thanks. I have downloaded a new skin, and it has the css codes there. Do i just copy and paste this into the css stylesheet or is there more I need to do?

You know - I truthfully don't know - but for sure, that is what I would try first. Let us know so that we can learn together!

I don't think you can do it by just copying the CSS codes.
The basic classes and ids may differ in both the skins.
So you have to code it yourself and upload the images to your host.
