The default layout is stretchable. This feature is provided
by snippets and JavaScript™.
If you consider adding your own widgets, you need to understand how
layouting is implemented by the HTML5 theme.
Important: While these topics assist you in
understanding layouting for possible modification, you should not
modify the default layout unless the change is critical.
Layout defaults
The HTML5 theme has both form and folder layout defaults.
Layout markup and data structures
This topic provides a description of the markup and the data structures needed to set up the layout.
Layout algorithm
The HTML5 theme uses a two-phase JavaScript algorithm to apply the layout.
