title: how to use HTML5 placeholder attribute with backward-compatibility in mind?
body: <p>I'd like to use HTML5's placeholder attribute (You can see it in cation in the newsletter at <a href="http://www.thoughtresults.com/navigation-timing" rel="noreferrer">Thought Results</a>). But when I use older browsers, of course, they don't render anything. I can use JavaScript to imitate it, but then, I shouldn't use it and it's done the old way. How can I have both HTML5 placeholder attribute, and at the same time simulate it for older browsers?</p>
