Re: how can I make different widget style ?
The short answer is yes. But it does get quite more complicated to more you customize your widgets. Take the bphome theme, for example, where you have your left, center and right columns (IDs). Each one of those has its own classes, so that’s another place where you’d modify your styles — plus, you can always add more classes for your widgets (you’ll definitely need to know some CSS for all of this). My best advice to you would be to download Firebug for Firefox, so that you can make realtime edits to your site. If all fails, leave another post on this forum and I’ll try to help you out more
