UK Plugs has a new, simple, lightweight design. Mainly because I wanted to practice more with the Foundation framework, and making static html sites without the bulk of CMS. The Foundation framework is a simple, responsive framework and it is very nice to work with.
They have a load of resources where you can get help, like their forums and help pages. Foundation has a bunch of pre-made CSS selectors, like columns and rows, which are all responsive. They provide a solid pre-made, responsive framework which allows you to create a custom website, a lot faster.
