ok guys i just found a really good one thats easy to use:
put this in your CSS file and play with the margins etc to set the position of the banner:
.box {
position: fixed;
left: 50%;
top: 50px;
margin: 0 0 0 -660px;
}
* html .box {
position: absolute;
}
put this in your site html
<div class="box">
Banner code
</div>
job done
