By default, all the .panel does is apply some basic border and padding to contain some content.

<div class="panel panel-default">
  <div class="panel-body">
    Basic panel example
  </div>
</div>

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.

<div class="panel panel-default">
  <div class="panel-heading">Panel heading without title</div>
  <div class="panel-body">
    Panel content
  </div>
</div>

<div class="panel panel-default">
  <div class="panel-heading">
    <h3 class="panel-title">Panel title</h3>
  </div>
  <div class="panel-body">
    Panel content
  </div>
</div>

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.
