Positioning Properties and Values

Below is a table of style properties and values for positioning. (I've included here only properties now supported by Internet Explorer and Netscape -- I'll add others when they are supported)

	Property	Description	Values	Example
Positioning Properties
	clip (not inherited)	Specifies an area of an element to be rendered transparent	rect (top right left bottom) where top right left bottom are auto or length values (pt, in, cm, px)	{ clip: rect (5pt auto auto auto) }
	height (not inherited)	Specifies the height of an element (most useful for scaling images; the aspect ratio will be maintained if width is specified as auto)	auto or length values (pt, in, cm, px) or percentage	{ height: 50px }
	width (not inherited)	Specifies the width of an element (most useful for scaling images; the aspect ratio will be maintained if height is specified as auto)	auto or length values (pt, in, cm, px) or percentage	{ width: 50% }
	left (not inherited)	Specifies the left position of an element positioned relatively or absolutely	auto or length values (pt, in, cm, px) or percentage	{ left: 2pt }
	top (not inherited)	Specifies the top position of an element positioned relatively or absolutely	auto or length values (pt, in, cm, px) or percentage	{ top: -2pt }
	overflow (not inherited)	Specifies the handling of a portion of element positioned relatively or absolutely that overflows into another element	clip (overflowed portion is hidden) or none (overflowed portion displayed) or scroll (to reveal overflowed portion)	{ overflow: clip }
	position (not inherited)	Specifies whether element can be positioned	absolute (in relation to the document); relative (in relation to the parent element); static (default--not positioned)	{ position: relative }
	visibility (not inherited)	Specifies whether element is visible (space for element is reserved in either case)	visible; hidden	{ visibility: hidden }
	z-index (not inherited)	Specifies whether element displayed above or below other overlapping elements (note that Netscape 4.0 handles this through the layer attribute	number (positive for above, negative for below, starting from 1; by default successive elements are assigned higher numbers)	{ z-index: 2 }
	white-space (not inherited)	Specifies whether element displayed normally, or a pre-formatted text	normal; pre	{ white-space: pre }
