How to make a liquid, centered, image with a caption overlay? - css

Question

I'm trying with CSS to display an image centered with a caption overlay, and a liquid capability when the browser window is too small (shrink to fit).
My current best attempt looks like the following HTML (using Google's logo as sample image)
<div align="center">
<div class="container">
<img src="http://www.google.fr/images/logos/ps_logo2.png" class="picture" />
<h3 class="caption">Image Caption</h3>
</div>
</div>
with the following CSS
.container {
position : relative;
max-width : 364px;
}
.picture {
border-radius:0.5em;
box-shadow: 0px 0px 0.5em #000000;
max-width:364px;
}
.caption {
position:absolute;
padding:0.25em;
top:1em; left:0; right:0;
color:black;
background-color:rgba(0,0,0,0.2);
text-align:center;
}
However, if it behaves centered as I want it to be for large browser windows, it doesn't shrink for small browser windows...
Also I don't need IE support, a WebKit-specific (iPhone/Android) would be enough, and I would like to avoid JavaScript if possible.

Just set the max-width to the container instead of the image and tell the image to be width:100%

<div class="container">
<img src="http://www.google.fr/images/logos/ps_logo2.png" class="picture" />
<h3 class="caption">Image Caption</h3>
</div>
.container {
position : relative;
max-width : 364px;
margin:0 auto;
}
.picture {
border-radius:0.5em;
box-shadow: 0px 0px 0.5em #000000;
width:100%;
}
.caption {
position:absolute;
padding:0.25em;
top:1em; left:0; right:0;
color:black;
background-color:rgba(0,0,0,0.2);
text-align:center;
}
You don't need the outer div, and align="center" is deprecated in HTML5, use CSS for alignment and positioning.
