<div class="module accordion expand"></div>

Then in CSS, you could match that element based on any one of them:

/* All these match that */
//AN_Xml:.module { }
//AN_Xml:.accordion { }
//AN_Xml:.expand { }

You can limit your selectors to match only if several of them are present, for example:

// Will only match if element has both
//AN_Xml:.accordion.expand { }

But what about other attributes?

Class names are unique in the ability outlined above. Other attributes are not treated as "multiple values" just because they have a space in them. For instance:

<div data-type="module accordion expand"></div>

This element just has a data-type attribute with a value of "module accordion expand", not three unique values "module", "accordion" and "expand". But let's say we wanted to be able to select elements based on individual values like we can with class names.

We could do it by using a "*" substring matching attribute selector which will match if the provided string appears anywhere in the value:

[data-type*="module"] {
//AN_Xml:
//AN_Xml:}

or only match when multiple of specific "values" are present:

[data-type*="accordion"][data-type*="expand"] {
//AN_Xml:
//AN_Xml:}

Ever better, use the whitespace separated selector (e.g. [data-type~="expand"]). That way you won't get burned by something like "expand" matching "expander" when you didn't want to.

[data-type~="accordion"][data-type~="expand"] {
//AN_Xml:
//AN_Xml:}

Works in IE7+ (because IE 7 was first IE to support attribute selectors)

With automatic updates enabled through Windows Update, customers can receive IE9 and future versions of Internet Explorer seamlessly

Windows XP gets IE 8
Windows Vista and 7 get IE 9

Presumably every new release will happen the same way. So when IE 10 goes final the next Windows Update will include that too for the OS's it will run on.

Auto Updating IE is a post from CSS-Tricks

My plan is to open a window the exact size needed to fit the image. Quick, easy, and perfectly good UX in my opinion. All you have to do is this:

window.open(path-to-image);

Actually it's a bit more complex than that. We need to pass in a bunch of parameters to get the window we want. Namely, the kind with as little chrome as possible. A top bar with a close button and that's about it.

window.open(path-to-image, null, 'height=y, width=x, toolbar=0, location=0, status=0, scrollbars=0, resizeable=0');

Example:

The tricky part is figuring out just exactly what height and width values to pass. You can't just ask the image what size it is. Well you can, but it will lie. It will tell you its current size, not its natural size.

var img = document.getElementById('screenshot');
//AN_Xml:
//AN_Xml:img.width;  // current size, not natural size
//AN_Xml:img.height; // current size, not natural size

To get the natural size, we'll create a new image in the magical ether of JavaScript, set its source to the source of the on-screen image, and then test its width and height. It will report correctly as it's untainted by CSS on the page.

var img = document.getElementById('screenshot');
//AN_Xml:
//AN_Xml:var magicEtherImage = new Image();
//AN_Xml:magicEtherImage.src = img.src;
//AN_Xml:
//AN_Xml:var padding = 20; // little buffer to prevent forced scrollbars
//AN_Xml:
//AN_Xml:// Values to use when opening window
//AN_Xml:var winWidth = magicEtherImage.width + padding;
//AN_Xml:var winHeight = magicEtherImage.height + padding;

I use jQuery on my site, so ultimately my code is like this:

$(".view-full-size").click(function() {
//AN_Xml:
//AN_Xml:  var mainScreenshot = $("#main-screenshot");
//AN_Xml:
//AN_Xml:  var theImage = new Image();
//AN_Xml:  theImage.src = mainScreenshot.attr("src");
//AN_Xml:
//AN_Xml:  var winWidth = theImage.width + 20;
//AN_Xml:  var winHeight = theImage.height + 20;
//AN_Xml:
//AN_Xml:  window.open(this.href,  null, 'height=' + winHeight + ', width=' + winWidth + ', toolbar=0, location=0, status=0, scrollbars=0, resizable=0'); 
//AN_Xml:
//AN_Xml:  return false;
//AN_Xml:
//AN_Xml:});

You can see it in action on single gallery pages like this.

Obviously it doesn't do much on mobile, so I just remove the button with a media query.
