3 * Language: add styling for elements that have a language attribute.
7 * Show the user that a 'lang' tag has been applied by adding a thin dotted
8 * border. We also append the value of the tag between brackets, for example:
9 * '(en)'. Since the html element has a 'lang' attribute too we only target
10 * elements within the html scope.
