Enable the module to find additional region and pane styles in Panels. Below is a list of those currently included. Please share and contribute your styles! :)
Panels Wrapper
Wrap your panes and regions with unlimited possibilities.
Go HTML5! Wrap your content in the newly defined tags.
Semantic DS is an add on for Display Suite that adds semantic layouts and field templates.
Layouts
Article - Article tag including regions for content ( a div ), header, hgroup, aside, figure and footer.
Figure - Figure tag including regions for figure (no extra wrapping tag) and figcaption.
No Markup - A single region for content that renders no wrapping markup, instead it just renders fields directly
Section - Section tag including regions for content ( a div ), header, hgroup, aside, figure and footer.
Fields
These fields replace the default wrapper divs on fields with semantic tags.
In order to use the Semantic DS fields, you must enable the ds_extras module and turn on "Enable custom field templates" at /admin/structure/ds/extras.
