+ //
+ // description:
+ // A BorderContainer is a box with a specified size (like style="width: 500px; height: 500px;"),
+ // that contains a child widget marked region="center" and optionally children widgets marked
+ // region equal to "top", "bottom", "leading", "trailing", "left" or "right".
+ // Children along the edges will be laid out according to width or height dimensions. The remaining
+ // space is designated for the center region.
+ // The outer size must be specified on the BorderContainer node. Width must be specified for the sides
+ // and height for the top and bottom, respectively. No dimensions should be specified on the center;
+ // it will fill the remaining space. Regions named "leading" and "trailing" may be used just like
+ // "left" and "right" except that they will be reversed in right-to-left environments.
+ // Optional splitters may be specified on the edge widgets only to make them resizable by the user.
+ //
+ // example:
+ // | <style>
+ // | html, body { height: 100%; width: 100%; }
+ // | </style>
+ // | <div dojoType="BorderContainer" design="sidebar" style="width: 100%; height: 100%">
+ // | <div dojoType="ContentPane" region="top">header text</div>
+ // | <div dojoType="ContentPane" region="right" style="width: 200px;">table of contents</div>
+ // | <div dojoType="ContentPane" region="center">client area</div>
+ // | </div>
+ //
+ // design: String

+ // the full width of the container, or "sidebar" where the left and right sides extend from top to bottom.
