 ### Explained...
 
 Notes on the markup above...
 
 * The `span[data-picture]` element's `alt` attribute is used as alternate text for the `img` element that picturefill generates upon a successful source match.
 * The `span[data-picture]` element can contain any number of `span[data-source]` elements. The above example may contain more than the average situation may call for.
-* Each `span[data-src]` element must have a `data-src` attribute specifying the image path. 
+* Each `span[data-src]` element must have a `data-src` attribute specifying the image path.
 * It's generally a good idea to include one source element with no `media` qualifier, so it'll apply everywhere - typically a mobile-optimized image is ideal here.
 * Each `[data-src]` element can have an optional `[data-media]` attribute to make it apply in specific media settings. Both media types and queries can be used, like a native `media` attribute, but support for media _queries_ depends on the browser (unsupporting browsers fail silently).
 * The `matchMedia` polyfill (included in the `/external` folder) is necessary to support the `data-media` attribute across browsers (such as IE9), even in browsers that support media queries, although it is becoming more widely supported in new browsers.
