I’m not much of a UI designer. I’m a good web developer. I’m good at java and started developing things on ruby on rails as well. I love jquery and love javascripting in jquery. The prob is i don’t know css much. At work, we have a UI guy who can do this. So there is no problem at work. But when it comes to things i want to develop personally i find it extremely difficult to get a nice UI. Any suggestions?
