The same as HTML DIV tag.

An extension. It has the same effect as <h:div xmlns:h="http://www.w3.org/1999/xhtml">. Note: a Window without title and caption has the same visual effect as Div, but Div doesn't implement IdSpace. In other words, Div won't affect the uniqueness of identifiers.

<div align="left" width="300px">
    <doublebox />    
</div>
<div align="right" width="300px">
    <doublebox />    
</div>
