Bit of a nit but a header following another header always feels wrong to me.

How would you feel about this as a HTML pattern - `<h2>Thimble <em>Webmaking made easy</em></h2>` - don't have to use an `<em>` but something similar.

You could even go full on HTML5 and have `<header><h2>Thimble</h2><p>Webmaking made easy</p></header>` - though you might need to throw in a `<section>` or '<article>' or two to make it a fully valid document.
