layout

The styling of a Web page, a form or a graphical user interface can roughly be divided in two parts: (1) defining the overall“grid” of the page or window and (2) specifying the fonts, indents, colors, etc., of the text and other objects. The two are not completely separate, of course, since indenting or coloring a text influences the perceived grid as well. Nevertheless, when one separates the parts of a style that should change when the window gets bigger, from the parts that stay the same, one often finds that the grid changes (room for a sidebar, extra navigation bar, big margins, larger images…), while fonts, colors, indents, numbering styles, and many other things don't have to change, until the size of the window becomes extreme.
