How do I customize PHPBB3?

[kanno]

What file(s) do I have to edit to change the style/layout of the forum?

Depending on how much you actually wanna change, the files in:

/styles/themename/templates - All html files
/styles/themename/theme - All stylesheets
/styles/themename/imageset - All images

The default style on a new install is prosilver, so in that case it would be like: /styles/prosilver/templates

There's not really an easy answer to what files specifically you need to edit, but in those locations all files regarding the looks will reside.

An easier way is probably to look for a pre-existing theme to install, and that matches up what you want.

Thanks for the reply Anna! Here is a picture showing what I want to get rid of:

What file does this exist in?

[Anna]

That should be "overall_header.html" in /styles/prosilver/templates/
