CSS can be used in creative ways, by using CSS attribute selection, it’s easy to isolate image tags without alt attribute and link tags without title and link attribute.
Note: support for these substring selectors is confined to Safari, Gecko-based browsers, Opera, and IE7/Win.
CSS Code:
<style type="text/css">
/*
style all images that have an alt attribute, thus
highlighting those images that are correctly formed
*/
img[alt] {border: 3px solid red;}
/*
to boldface the text of any HTML hyperlink that
has both an HRef and a title attribute
*/
a[href][title] {font-size:200%;}
</style>
