Not taking vertical space in strict mode, but is taking vertical space in quirks mode

Here's the relevant piece of code.

<div style="position :relative;heigh t:506;width:700 ; z-index:1;
background-image:url(image s/Mat-Tan.png);">
<div style="position :absolute;z-index:2; height:0; width:0;">
<img src="images/Frame-Brown-Land.png" alt="" />
</div>
<div style="position :absolute;top:1 00px; left:125px;">
<img src="images/poster1.jpg" alt="" />
</div>
</div>

In strict mode, anything that follows this appears below the output
(and the background image isn't displayed). In quirks mode, which I'd
prefer to avoid, the output is as I expected (the basic idea is to
simulate the appearance of a framed/matted poster). Any ideas what I'm
doing wrong with my css?

Found it. Duh, I need to give UNITS on that.

Never mind...
