This is a very basic and clean Plone theme that uses HTML5 tags in your structure and gives you a Semantic HTML to start your projects.
Instead a lot of div>tags, this theme uses new HTML5 tags like header> section> <nav> and <footer>
CSS Reset
Beyondskins HTML5 use Normalize.css to reset the styles. Normalize.css makes browsers render all elements more consistently and in line with modern standards. It precisely targets only the styles that need normalizing.
Grid
Beyondskins HTML5 doesn't use any grid system, mainly becouse the actual grid systens make a mess in your html, adding a lot of non semantical tags. And becouse you don't need a grid system to create a website with 2 or 3 columns.
To change columns size, just edit grid.css file included ins this package:
#main {width: 100%;}
#main-content {width: auto;}
#column-one {width: 16%;}
#column-two {width: 30%;}
If you need a grid system, just plug your favorite grid system folowing their instructions. With a littlo mess in the HTML file you can make any modern grid system to work here.
