Visual format meta info
Additional meta-info can be added in the form of comments. Using this meta-info, you can instruct the viewer to for instance use a specific aspect ratio or a specific color for a sub-view:
//viewport aspect-ratio:3/1 max-height:300
//colors red:#FF0000 green:#00FF00 blue:#0000FF
//shapes red:circle green:circle blue:circle
H:|-[row:[red(green,blue)]-[green]-[blue]]-|
V:|[row]|
Meta-info is also processed by renderers. If you want to set the meta-info only for previewing purposes, then prefix it with a -. The following example sets the max-width and max-height for previewing a mobile layout. The actual layout renderer will ignore this meta-info.
//-viewport max-width:320 max-height:500
//heights header:44 footer:44
V:|[col:[header][content][footer]]|
H:|[col]|
