Menu
I have an image I'd like to show in a browser such that:
I do not want to use JavaScript; what's the best/most semantic HTML and CSS to do this?
Update I've been asked for clarification regarding semantics: the image is content; the only content within the HTML.
@GionaF ideas got me to a happy (and very simple) solution:
<!DOCTYPE html>
<head>
<title></title>
<LINK href="test2.css" rel="stylesheet" type="text/css">
</head>
<body>
<div>
<img src="photo.jpg" alt="photo" />
</div>
</body>
img {
max-width:100%;
max-height:100%;
position:absolute;
top:0; left:0; right:0; bottom:0;
margin:auto;
}

You can achieve it in many ways, but i can't be "semantic" without knowing the context (is the image the main/only content of the page? is it in the middle of a blog post?), so i'll go for a div.
position:absolute; + margin:auto;

}
#container {

position:absolute;
top:0; left:0; right:0; bottom:0;
margin:auto;

Be careful for how IE8 renders height:auto;, may not keep the ratio.
Edit: i just realized that you wrote "without adjusting the aspect ratio of the image". If you really don't want to keep the ratio, it's easier ... but do you really mean that?
