As of Microsoft® Internet Explorer 6, when the !DOCTYPE declaration specifies strict standards compliance, inline elements will ignore the width and height properties, and setting the width and height properties will not cause the element to have layout.

Setting the contentEditable property to true will cause an element to have layout.

BODY, IMG, INPUT, TABLE and TD elements always have layout.

Example

The following example shows how to use the hasLayout property to determine whether an object has layout.

<DIV ID="oWidthSet" STYLE="width:100%">
DIV element A has its width set to 100%.</DIV>
<DIV ID="oNotSet">DIV element B is not positioned,
and neither its height nor width is set.</DIV>
<P>Which DIV element has layout?</P>
<BUTTON onclick="alert(oWidthSet.currentStyle.hasLayout)">
DIV Element A</BUTTON>
<BUTTON onclick="alert(oNotSet.currentStyle.hasLayout)">
DIV Element B</BUTTON>
