Форумы / Cotonti / Skins / create box in ccs file

the images aint the problem, I'm better with Photoshop then with ccs files :) or English for that mather :P

I tried this

#content #mlSide { float:left; width:550px; }
#content #mlSide .mlboxHD { color:#3E606F; background: url(img/SED-Light_lBoxHD.gif) no-repeat; width:250px; height:35px; line-height:35px; vertical-align:middle; font-size:.90em; text-transform:uppercase; padding:0 0 0 10px; font-weight:bold; }
#content #mlSide .mlboxBody { width:250px; background:#FFF url(img/SED-Light_lBoxFT.gif) no-repeat bottom; min-height:20px; padding:10px; margin-bottom:10px; }

And

#content #mrSide { float:left; width:550px; }
#content #mrSide .mrboxHD { color:#3E606F; background: url(img/SED-Light_lBoxHD.gif) no-repeat; width:250px; height:35px; line-height:35px; vertical-align:middle; font-size:.90em; text-transform:uppercase; padding:0 0 0 10px; font-weight:bold; }
#content #mrSide .mrboxBody { width:250px; background:#FFF url(img/SED-Light_lBoxFT.gif) no-repeat bottom; min-height:20px; padding:10px; margin-bottom:10px; }

After that i don't exactly know where to put the div in the index file
