如何更改 Bootstrap 中手风琴选项卡的背景颜色？

Question

我正在尝试更改手风琴上选项卡的背景颜色。当我在 CSS 中更改背景颜色时，它只会更改文本后面的颜色，而不是整个内容。

这是我的代码的一部分：

 <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">
            Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. 3 wolf moon officia aute, non cupidatat skateboard dolor brunch.

    </div>
    </div>
</div>

Answer 1

如果只有文本的背景发生变化，您可能正在更改锚标记的 background-color ，而是使用以下 CSS 选择器更改 background-color 的 panel-heading :

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