Layering Images
The code about to be described can make pixel perfect content
placement possible.
Say you have two images, like the two images below:

But, you want them to be on top of each other to form a cross
like the one below:
How did I do that? Magic, you say? Nope, all I did was add a
couple of <div> tags. Here is the code:
<div id="top" style="left: 500px; top: 485px;
position: absolute">
<img src="image1.gif"> </div>
<div id="under" style="left: 500px; top:
485px; position: absolute">
<img src="image2.gif"> </div>
First, you must give your div a name, which the id attribute
does. The style attribute will define the position of the whole
layer of content the falls inside the <div> tag. There
are only a few things that you have to remember:
The left function positions the image x number of pixels from
the left of the browser to the left side of the image.
The top function positions the image x number of pixels from
the top of the browser to the top of the image.
Remember to put position: absolute in because if you do not,
the position will default to the position: relative setting
which is more difficult to work with and can cause some varying
placements in different browsers.
That's all you need to know. Layer it up!
