visible and display in javascript

Can any tell me what is difference between Visibility and display in javascript ?
Any link may helpful .....

 

sure. this belongs in the css forum, really. visbility can be visible or hidden. it just hides the element from view - imagine that you have a box - layer - div. width 50, height 50, something like that:

foo
<div style="width: 50px; height: 50px;">
bar
</div>
foo again


this will render on-screen as:

foo
bar


foo again

if you change the visibility of the layer to hidden, it will keep it's allotted screen space and render this:

foo



foo again

if you, however, change the display to none instead, it will render as this:

foo
foo again

basically, it hides it and releases the space that it takes so any elements around it that float or whatever, reclaim the gap.
you have several modes of display also, block, inline etc etc. they all have css implications. hope this explains it somewhat
