Each skin is made up of 'Panes' for arranging your content in your website, depending on the skin package these panes can be adjusted to suit the size of your content -again by using the designer tool and not by editing the html or css files directly. Unused panes will collapse where available so you don’t have to have different skins for multi-column layouts, just use the panes you need to. Also, many of our skins will expand to fill the width of the page (or again can be adjusted using the editor), so large modules or administration sections will not drastically ‘break’ the page layout, and you will not need separate skins for these sections.
