left left

Note: Accepts either an integer (assumed pixel units) or a percentage string.

Examples: left=10 or left="20%"		 left or pixelLeft

Note: pixelLeft accepts a string which specifies measurement units; e.g. pixelLeft="10px" whereas left accepts an integer and assumes pixel units; e.g. left=10.
top top

Note: Accepts either an integer (assumed pixel units) or a percentage string.

Examples: top=10 or top="20%"		 top or pixelTop

Note: pixelTop accepts a string which specifies measurement units; e.g. pixelTop="10px" whereas top accepts an integer and assumes pixel units; e.g. top=10.
clip clip.top
clip.left
clip.right
clip.bottom
clip.width
clip.height

Each dimension of the clipping coordinates is its own property, as seen here. Changing any property immediately causes the on-screen clip to change.		 "rect(top right bottom left)"

To change the clip in MSIE you must redefine all clipping coordinates. The syntax can be a bit confusing.

Example:
document.all.blockname.style.clip ="rect(0 25 25 0)"
visibility visibility

May contain any of "inherit", "show", or "hide"		 visibility

May contain any of "inherit", "visible", or "hidden"
z-index zIndex

Any non-negative integer.		 zIndex

MSIE allows negative integers, but you may as well stick with positive for the sake of Netscape.
background-color bgColor

Examples:
document.layers["blockname"].bgColor ="black"
document.layers["blockname"].bgColor ="#000000" 		backgroundColor

Accepts string containing pre-defined color name or hex RGB triplet.

Examples:
document.all.blockname.style.backgroundColor ="black"
document.all.blockname.style.backgroundColor ="#000000"
background-image background.src

Example:
document.layers["blockname"].background.src ="images/tile.jpg"		 backgroundImage

Example:
document.all.blockname.backgroundImage ="images/tile.jpg"
