So why should any of us even care about the hasLayout property? Because many
Internet Explorer display inconsistencies which can be attributed to this property.
In most cases, the issues caused by elements that lack a layout are easy to spot: the
content is often misplaced or completely missing. For example, when an element,
such as a div, that doesn??™t have a layout by default, contains floated or absolutely
positioned content, it will often exhibit strange and buggy behavior. The types of
strange behavior that can arise are varied, and include such behaviors as missing
or misplaced content, or elements that fail to redraw fully while a window is moved
or scrolled.
