How do I change the background-color of an accordion tab in Bootstrap?

Question

I am trying to change the background color of the tabs on my accordion. When I change the background color in CSS, it just changes the color behind the text and not the entire thing.

Here is a segment of my code:

<div class="panel-group" id="accordion">
    <div class="panel panel-default">
        <div class="panel-heading">
        <h4 class="panel-title">
            <a data-toggle="collapse" data-parent="#accordion" href="#collapseOne">
      Collapsible Group Item #1
            </a>
        </h4>
        </div>
        <div id="collapseOne" class="panel-collapse collapse in">
        <div class="panel-body">

Answer 1

You are probably changing the background-color of the anchor tag if only the text's background is changing, instead, use the following CSS selector to change the background-color of the panel-heading:

.panel-default > .panel-heading {
    background-color:#000;
}
