Today I found out that the clearfix hack doesn’t do so well with Facebook. To avoid scrollbars in a facebook tab:
body, html {
overflow:hidden;
}
and before the closing body tag:
<div id="fb-root"></div>
<script type="text/javascript" src="https://connect.facebook.net/de_DE/all.js"></script>
<script type="text/javascript">
FB.init({
appId : 'APP_ID',
status : true,
cookie : true,
xfbml : true,
oauth : true
});
$(document).ready( function(){
FB.Canvas.setSize({ height: $('body').height() });
FB.Canvas.scrollTo(0,0);
});
</script>
