Format description and guidance

Fluid skins are a responsive high impact format, composed of three individual HTML5 panels - a left panel, a right panel (the side panels), and a top banner. The side panels fill the space between the sides of the page content and the window edge, and scale responsively with the height and width of the browser. The topbanner fills the gap between the side panels, above the page content. The content within each panel should scale responsively based on the width and height of the individual panels.
