The idea behind the theme is to create a minimalist, lightweight template like any of the core themes such as Bluemarine and Garland and one that works “out of the box”. It you are using the core modules then it shouldn't be necessary to alter the CSS (unless you want to!) although you'll probably want to use one the six core themes for the administration section as I haven't paid much attention to that side of matters.
It is a tableless design that should work in all major browsers including Internet Explorer 6. The colours are black and white, with a splash of orange and violet.
Clean A is fixed width and can either be two or three columns.
It contains the following regions: Header, left sidebar, content, right sidebar and footer.
