SpiegelMagazine makes use of the famous 960 grid system. The 960 grid system is an effort to streamline web development workflow by providing commonly used dimensions, based on a width of 960 pixels. The 12-column grid which is used for this theme is divided into portions that are 60 pixels wide. Each column has 10 pixels of margin on the left and right, which create 20 pixel wide gutters between columns. This normally leads to 10px margins to the far left and right side which I felt is too few. So I added 20px margins to both sides which makes the whole grid not 960 but 980px wide to be correct.
