I have a problem getting my custom css to work. I created my own template and copied the css file. Then I changed the first rule of css into this, but it doesn't show up on my website.

div#b2jcontainer.b2jcontainer
{
width: ;
padding: 30px;
overflow: visible;
margin: auto;
background: #ffffff !important;
border: none 0px #ffffff !important;
font-family: inherit;
color: #000000 !important;
font-weight: 300;
}

Any ideas?
