0 HTML5 placeholder Attribute

HTML5 has introduced many features to the browser;  some HTML-based, some in the form of JavaScript APIs, but all of them useful.  One of my favorites if the introduction of the placeholder attribute to INPUT elements.  The placeholder attribute shows text in a field until the field is focused upon, then hides the text.

Example:

<input id="name" name="first_name" placeholder="Your first name..." type="text">
