How come I cannot get this image overlay to work?

A transparent film with a description is supposed to appear when I hover over the image. What is wrong with my CSS?

HTML

<!DOCTYPE html>
<html>
    <head>
        <link rel="stylesheet" type="text/css" href="imgoverlay.css" media="screen">
    </head>
    <body>
            <div id="imgcont">
                <img src="frog.jpg" alt="froggy">
                <div id="frog">
                This is a frog 
                </div>
            </div>
    </body>
<html>

CSS

#imgcont {
    position:relative;
    width:200px;
    height:150px;
}



img {
    width:200px;
    height:150px;
    position:absolute;
    z-index:0;
}

#frog {
    position:absolute;
    width:200px;
    height:150px;
    background: rgba(0,0,0,0.45);
    z-index:-1;
}

#frog:hover {
    position:absolute;
    width:200px;
    height:150px;
    background: rgba(0,0,0,0.45);
    z-index:1
}

Hi,

in #frog:hover statement you want to tell browser, that when you hover your mouse over the image, the z-index will change and the overlay will be visible (will be top layer)...

The problem is that you can't hover on #frog element, as it is hidden behind image.

So you can try to change your code, based on what I wrote before, like:

#imgcont:hover #frog {
    z-index:1;
}

so when you hover over #imgcont the z-index in #frog will be 1. I was expecting that #imgcont img:hover should work also, but didn't, not sure why...

you forget the semi-colon mark (;) in the end of "z-index:1" declaration
