jQuery: How can i create a simple overlay?

Question

How can I create a really basic overlay in jQuery without UI?

What is a lightweight plugin?

Answer 1

What do you intend to do with the overlay? If it's static, say, a simple box overlapping some content, just use absolute positioning with CSS. If it's dynamic (I believe this is called a lightbox), you can write some CSS-modifying jQuery code to show/hide the overlay on-demand.
