javascript image overlay over a specified div

Question

i am new at javascript. very new actually, this ought to be my first script. can anyone explain to me how to make a transparent overlay over any specified fixed width regio

Answer 1

You can define the overlay such as

...contents...

and define the dimensions and position and z-index etc... in CSS

.myoverlay {
   position: absolute;
   display: none;
   ...
}

I don't quite see the need for JavaScript just yet, but I guess you will want to use JS to toggle the overlay's display attribute on/off.

Is this roughly what you're after? Sorry for unintentional syntax mistakes, for this is untested code purely off the top of my head. Just to give you an idea.
