Hi, I have an annoying horizontal line between my banner div tag and my main body div tag… but not my menu and other links div tag. I can’t fathom why, I am not a professional as you can probably tell 
any help much appreciated. Here is my .css code so far!
#container {
width:968px;
margin: 0 auto;
overflow: hidden;
}
#banner {
overflow:hidden;
border:0px;
padding:0px;
margin:0px;
}
#links{
background-color:#FFF;
}
#menu {
width:auto:
}
#maincontent {
width:968px;
height:800px;
}
#left {
float:left;
width:100px;
overflow:hidden;
}
#latestnews {
position:relative;
float:left;
width:220px;
overflow: auto;
background:#FFF;
}
#twitter {
float:left;
clear:both;
width:220px;
height:300;
}
