Can DHTML do this?

complex mouseovers

[Quarfelburg]

Is it possible to make a mouseover in DHTML or any other langauge that does the following:

Adds a blue layer above the image with an opacity of 60% making the image somewhat transparent and then writes text over the image.

If this is possible any sample code / tutorials would be greatly appreciated =)

Adds a blue layer above the image with an opacity of 60% making the image somewhat transparent and then writes text over the image.

You can do this using CSS2 and some JavaScript... although, would it just not be better to swap the original image with the new semi-opaque with text image?

Also, it's important to remember that DHTML is not a language. It is merely CSS objects being manipulated by JavaScript using the Document Object Model.

It would be much easier, but bad for load time. How will the load time be if this were done in CSS + JS?
