my problem is that i need to give below min-height to set in different browsers

>min-height: 180px in chrome
>min-height: 135px in opera
is there any code which give me generic solution for that.
or trick like -moz- and -webkit- anything.
My advice would be to fix your CSS so you won’t need to do that. This browsers should display your page almost identically, so you are probably doing something very weird.
With that being said, the easiest solution (if you absolutely, positively) need to do this is to use CSS hacks to target different browsers. See here for examples: http://css-tricks.com/snippets/css/browser-specific-hacks/
