An <hx class=".panel-title"> should inherit color from .panel-heading

Created by: maniqui

The class .panel-title, which is usually applied to a heading element (<hx class="panel-title">) doesn't inherit the color defined for .panel-heading, which is defined in this rule:

.panel-primary > .panel-heading {
  color: #ffffff;
}

Instead, it currently inherits its color from the one defined in the rule h1, h2, h3..., .h1, .h2, .h3... {}.

My opinion is that the .panel-title class should inherit its color from .panel-heading class.

The change is simple. In panels.less, do:

.panel-title {
  margin-top: 0;
  margin-bottom: 0;
+  color:inherit;
  font-size: ceil((@font-size-base * 1.125));
  > a {
    color: inherit;
  }
}
