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. However, the font sizes of <h1>-<h6> are overridden by .panel-heading.

For proper link coloring, be sure to place links in headings within .panel-title.
