css related: layers

I'm trying to learn this css thing.

I followed this tutorial that "asked" me to put my text (or other elemente) within a div id tag and name it. Then from the css file doing a #name I can manipulate the element in the html page.

My question. I've noticed that when I place the div tag, in essence I'm creating a layer, and by naming the element with the id thingie, I am naming the layer. Does anyone know if this is correct ...or normal ...or am I doing something wrong?

Any comments will be very much appreciated. Thanks.

You are only making the element a "Layer" is you set its position to
"absolute". Consider the following scenario:

1. You make a DIV:

<div id="mydiv">
My text or whatever is inside the div
</div>

2. You make a style:

#mydiv {
padding: 20px;
background-color: gray;
width: 300px;
}

This DIV is static. In "dreamweaverspeak" it is not a Layer.

But if you make this style:

#mydiv {
padding: 20px;
background-color: gray;
width: 300px;
position: absolute;
top: 0px;
left: 0px;
}

....then you have a "Layer" that is positioned flush in the top left corner
of your window.

You are absolutely correct.

With the ID selector you identify an element to be an *unique instance* in a document.

The term 'layer' is a DW-invented concept (well, NN4 used it too). In DW, a
layer = absolutetly positioned DIV with a z-index. So, it's just a DIV with
some very specific style attributes.
