Windows 7: Opera appearance modifications

Can anyone tell me how to colour in trimmings and borders black and then change the font colour. I want everything black with orange writing. I've seen it and I lik it, I just cant figure out to do it?

Also, when I go to my find new skin page, it is really messy. Lots of bold bright borders and lines and broken lines. Is very hard to read. What have I done?

Also, how do I set up utorrent to download through opera?

Those are things you have to learn on your own as this is a Windows 7 Forum.
Not trying to be rude

But this is in the browsers category? Is it not a browser?

You have made a mess
my suggestion is to download a Opera snapshot & install it as a portable & use this to learn how to customize Opera you can run it alongside your main Opera installation without any conflicts & is very easy to backup by just copying the install folder.
11.62 for Windows instructions on the page for installing the portable version ( "Stand-alone installation (USB)" )

To undo any changes you have made to Opera you need to delete the operaprefs.ini file open the Menu >Help & select About Opera , Look for Paths > preferences then Navigate to the location using Windows Explorer & delete the file & restart Opera the file will automatically recreated with the default settings.

A nice dark skin & some info about skins
My Opera - Opera Skins by TA5K

My advice would be to just use one of the hundreds of skins already available or learn how to make your own .

When you click on a link to a torrent you are given the choice of using Opera or the default torrent program.

Thanks guys. Am learning slowly
