Most of web designers should know about an awesome project HTML5 Boilerplate, which thanks to Paul Irish and other contributors puts a lot of wisdom into a package which is a very good starting point for any web project. At least those designers who prefer to hand-code their HTML and CSS. I noticed on H5BP Wiki that it was used in a few other projects or CMSes, and was converted into a WordPress theme as well, but there was no Joomla template based on it. Also, since BestJoomlaHosting website required an update (from Joomla 1.0 to 2.5) it also needed its template to be upgraded, so it seemed like a good practice.
Keep in mind that our H5BP4J template is very basic, and should be treated as a starting point for someone who knows CSS, HTML and a little bit of PHP and is trying to create his own template. And it was written for Joomla 2.5 only.
Download the template from GitHub: H5BP4J version 0.1 or browse the code.
