Im working on a image map a previous dev created as part of a navigation. It will feature the UK map cut up into regions to navigate to them parts of the site. The previous dev used img maps, but image maps dont use css correctly as image maps are a legacy method.
Bellow is the code

We need each of the areas to change colour on hover. would it be best to re write this using div and ul/li with absolute positioning. Or is it possible to change the ukmap.gif with jquery/javascript on mouse over? as then i could have the same image with different areas blocked colour and change the image to mimic a css:hover, i dont want to undermine previous peoples work while at same time not wasting time rewriting it if a simple jquery hack can select these

Reset to default 6"image maps are a legacy method" -- untrue. HTML image maps are fully supported by the HTML 5 spec.
CSS simply doesn't apply to imagemaps.
Try ImageMapster, a jquery plugin designed exactly for this purpose.
Here's a basic usage (same problem as the other answer - the areas don't match right, I couldn't easily find an accurate imagemap of the UK and don't have your source image that your areas match). But you get the idea.
http://jsfiddle/VcGXL/
// basic implementation of hotspots with ImageMapster
$('#mapimage').mapster(
{
fillColor: 'ff0000'
});
If you don't want to restart everything you could do the following: Add the hover code to each area, and change the source of the image.
$('#southeast').hover(
function() {
$('#mapimage img').attr('src', 'http://www.groupswele.co.uk/maps/uk_map.gif');
},
function() {
$('#mapimage img').attr('src', 'http://www.alert24uk./ESW/Images/uk-map.gif');
}
);
Here's a fiddle of this method (rollover southeast at the bottom right)... Images do not correspond to the mapping of course.
By doing this, you will see a blank image temporary... until the image loads.
There are ways to prevent this, like using a spritesheet instead. If interested, I can work up an example for you.
This is an easy way. There are other options. HTML5 canvas if your website is for recent browsers.
In fact the default display for area in none so you have to style it to display:block first, so put this CSS rule to change the cursor over the maps areas:
area{
display:block;
cursor:hand;
}
Sorry to jump on this question late in the game but I have an answer for irregular (non-rectangular) shapes. I solved it using SVGs to generate masks of where I want to have the event attached.
The idea is to attach events to inlined SVGs, super cheap and even user friendly because there are plenty of programs for generating SVGs. The SVG can have a layer of the image as a background.
