Jquery overlay when image clicked

Question

Not the best with jquery, can someone suggest a general approach for what i am trying to achieve please? I have a grid of photos, and when they are clicked on, an opaque overlay will be animated on top of the entire picture, the overlay will contain some dynamically set text. I have the images, and the onclick handler working, just trying to figure out the best way to apply the overlay. thanks

Not very pretty semantically, but should get the job done : Let's say your imgs are 200x200.

<div class='imgcontain'>
<img src='yourimg' alt='' width='200' height='200'>
<p>Your text>/p>
</div>

<div class='imgcontain'>
<img src='yourimg' alt='' width='200' height='200'>
<p>Your text>/p>
</div>

<div class='imgcontain'>
<img src='yourimg' alt='' width='200' height='200'>
<p>Your text>/p>
</div>

// etc...

Then, the CSS :

.imgcontain
{
position: relative;
width: 200px;
height: 200px;
overflow: hidden; // not sure you want to makes the overlay just show or slide from top. This is useful only if it should slide.
}

.imgcontain img
{
position: absolute;
width: 200px;
height: 200px;
top: 0px;
left: 0px;
z-index: 2;
}

.imgcontain p
{
position: absolute;
display: block;
width: 200px;
height: 200px;
top:  0px; // if slide from top, -200px
left: 0px;
background: rgba(0,0,0,0.5) // or a background image like a transparent png with repeat
z-index: 1;
}

.imgcontain:hover p
{
z-index: 3; // if slide from top, top: 0px
}

This is a pure CSS solution, without animation, works for users with Javascript of.

If you want then to animate it using Jquery :

$(.imgcontain p).hide().css('z-index','3'); // on ready, hide the overlay. Maybe throw the .css() in callback.

then, on click/mouseover

$(.imgcontain).click(function()
{
$(.imgcontain p).show();
});
