CSS image map

[Chris]

I'm going to be making a CSS image map for a site. This is a system that functions just like an HTML image map but uses CSS to put active spaces on top of an image using absolute positioning.

I'm not a CSS ninja so I wanted to get some clarification on this.

Is absolute positioning always from the window boundaries, or can it be from within a div, or is that relative positioning?

So if I put the image as the BG of a div, then put my CSS links in the div, I'd need to use position: relative or position: absolute if I wanted to do the positioning based on pixels in the image, as opposed to pixels on the screen.

Then, with positioning, what part are you positioning? Do I give the position of the top left corner, or the center?

Absolute positioning is always from within the window boundaries unless the item you're positioning is in side of another parent container.

Here is a link I dug out of my bookmarks that may help? http://www.webreference.com/html/tut...html#SUBHEAD-1

I'm done with this... but I did run into 1 issue.

Firefox cannot handle a css file with a query string. With 300+ individual dynamic definitions making the css imagemap I figured it called for a separate file. So I made a css file, used ForceType to have it processed for PHP, and put the PHP code in it to take a query string and generate the right CSS.

Worked great... in IE. firefox would balk at the query string (and yes, I figured out it WAS the query string, I copied the output and put it in a file without a query string and it worked fine). PITA.

So I have to echo all the CSS definitions on the page.
