Easily add a heading container to your panel with .panel-heading. You may also include any <h1>-<h6> with a .panel-title class to add a pre-styled heading.
For proper link coloring, be sure to place links in headings within .panel-title.
Wrap buttons or secondary text in .panel-footer. Note that panel footers do not inherit colors and borders when using contextual variations as they are not meant to be in the foreground.
Like other components, easily make a panel more meaningful to a particular context by adding any of the contextual state classes.
