I just found "blockbody" and "blockhead". They are :
Code:
<link rel="stylesheet" type="text/css" href="css.php?styleid=1&langid=1&d=1261137425&td=ltr&sheet=vbulletin.css,popupmenu.css,vbulletin-chrome.css,components.css,vbulletin-formcontrols.css" />
Please check attached image. class "tborder" and "tcat" does exists in Main CSS.
May i please know how do i use those classes? or at least syntax to include that css.
