css - background-color on specific div appearing on whole page -

i'm working on page: http://broadcasted.tv/

my headings have following (i know should class, doing testing)

 #title-container {  background-color: #333;  color: #fff;  margin-top: 15px;  } 

it works fine everywhere except there http://broadcasted.tv/user/2/albertmarch/

and can't figure out why heading whole page... missing div ??

any appreciated

thanks!

the background goes away if add clear:

#title-container {     background-color: #333;     color: #fff;     clear: both;     margin-top: 15px; }
