Create This Shape Using CSS

Folks , here is my problem. A while back I created an application that had a number of images which the user would roll over and a red outline border would highlight this area & this was achieved using CSS. Now at that time I found through trail & error that css was (by far !) more bandwith friendly that slices & tables that I originally tried in fireworks, now this was all great as long as my areas were all squares or rectangles...

So here is the question, as I am a slow learner..please look at the attached image and tell me (preferably a small sample from you would be the beeees kneeeees) can I create the blue line using CSS ? I'm feeling I may have to go down the fireworks/photoshop route again but really would prefer to avoid this if at all possible !!

CSS is extremely linear and wouldn't support the angles which the rectangle resides at.  
You may however be able to do it with a combination of jquery and CSS.  However, I think that you'll find it's much easier going with the Photoshop/Fireworks option and slicing it.  
Just because you need to use an image does not mean you need to use tables. Create 2 images, one for the mouse over state, and then you can use CSS to position the image and do a mouse over effect.
Hi mrmad1966,
Your username tells it all :)
Can you elaborate on what you're trying to achieve ?

If you only needed the blue line or a clickable area it can be done using an image map and setting a css style for that map, otherwise it's not possible using css
And an example for you :)
