In the past, the <div> code has worked perfectly fine for me. I have been able to successfully line up image background with the iframe relatively easily; however:

The iframe being influenced by the <div> code "refuses" to move above the upper half of the screen. It may just be my computer (Windows 7 Laptop), but I highly doubt it. The coding I am using is:

<div style="position:absolute;center:50;top:40;width:400;height:200">
<iframe name="iframe1" iframe bordercolor="6DCFF6" style="border-width:0px; border-style:solid; border-color:6DCFF6;" src="http://telemachus.webs.com/evolution2.htm" align="center" height="400" width="200" hspace="0" vspace="0" frameborder="0" scrolling="auto"></div>

This same code has been used before successfully:

As also seen on the web-page in question, it appears to have added unnecessary space to the bottom of the screen. Scrolling down will leave the viewer with nothing but gray to look at. I am unsure why this is occurring, seeing as it has not happened before.

There is no property called 'center'. The other values need units.

I have already tried "left" and "right", and yet it still won't rise onto the top half of the page.

As for values, any suggestions?

I just meant you should correct the errors. There are a lot more of them. You can use the validators to find them.

Now that I have looked at your other pages that you say look as you want I don't understand the problem. I don't see what's different. What exactly is it that you want higher up?
