widget borders

hi ive looked through your help but cant find the solution to my problem exactly. id like to remove borders on SOME widgets on my right side bar but not others. i found in another thread the solution to remove ALL borders - #secondary .widget { border: none; box-shadow: none; } which i put in my custom css area. what i would like to do now is have some areas with borders and not others eg text-2 with a border and not text-3 for example. i tried #text-2 { border:#000 solid 1px; } but doesnt work. (i know just a tiny amount about internet programming! - im NOT a programmer) could you help? my test site is at garethrawlins.com thanks for your time.
