add my own template

hello frnds i have a templet in css formate its fully a website css template can i use this template in this forum.

Yes you can use

Admin Panel -> Advanced Mode -> Display -> Colors -> CSS Stylesheet -> "paste the code there" and click submit

its working when adding some css code but when i m adding a full css code with a diff layout its not working ..
when i m saving this come there is no effect on my forum.
what to do.

Okay, I'm really stupid when it comes to CSS but maybe it matters what version the forum is in where you're pasting the CSS.
And maybe try out the two options beloew the CSS box.
