Trigger transitions without javascript in CSS on page load

Question

I would like to increase the width of a bar with a CSS transition but don't like to trigger it with a hover event ( like http://jsfiddle.net/TFHn9/ )

I just would like to have an instant animation (when the page loads) - without Javascript of course.

Any chance to achieve that?
