Test: abbr present in DOM?

JavaScript fired after page load to check presence of abbr in Internet Explorer's DOM.

Expected behaviour/results

• An alert box should show that there are two abbr elements present.
• Each abbr should have at least one child text node, shown in an alert box.
• Each abbr has a title attribute, which should be displayed one by one in an alert box to check that they can be accessed.
• JavaScript is used to set a green background on each abbr to check whether or not styling is permitted.
