Using unsemantic to customise page display

Hi Tom,

Just wondering how I can 'tap' into the framework behing GP (Unsemantic) to further customise my pages and provide more custom columns within the visual page editor. Also I am hoping for a way to use custom class syntax (like you can in foundation) to remove some div elements from display on mobile devices.

I am aware that most elements will just fold down into 1 column grids and stack on top of each other but I want to remove some divs from the flow entirely when viewing on a mobile device.

I know you don't have a layout or page builder (and for good reason considering the load it puts on web pages) but at the same time, I am looking to further customise particular pages (this one is the homepage) by inserting extra columns/grids to layout information and even perform some additional markup on them.

The downside to this, of course, is that it makes it quite difficult for a client to update without having a good solid foundation in editing/writing HTML (this is usually where the page builders come in). I'd love to hear some suggestions regarding this particular problem.

Thanks
