Question

我正在尝试更改手风琴上标签的背景颜色。当我在CSS中更改背景颜色时，它只会改变文本背后的颜色而不是整个颜色。

以下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">

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

Answer 1

如果只有文字的背景发生变化，您可能正在更改锚标记的background-color，而是使用以下CSS选择器来更改background-color panel-heading }：

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

Answer 2

您可能需要为面板创建自己的自定义上下文状态类。 Bootstrap comes with a bunch built in，但如果你想要完全不同的东西，你需要添加一个。例如，这将为名为flashy的面板创建一个新的上下文状态类：

.panel-flashy {
    border-color: #FF934F;
  }
.panel-flashy > .panel-heading {
     color:#fff;
     background-color:#FF934F;
     border-color:#ff934f;
}

HTML code：

     <div class="panel panel-flashy">
        <div class="panel-heading">
           <h3 class="panel-title">Flashy Panel title</h3>
        </div>
        <div class="panel-body">
           Panel content goes here
        </div>
     </div>

Answer 3

Bootstrap有内置样式：

变化 <div class="panel panel-default">

要 <div class="panel panel-primary">

所有其他Bootstrap颜色均适用，因此panel-success panel-warning等见这里：Bootstrap Contextual colors

任何其他颜色都需要你编写一个类来补充引导类，例如

.panel-turquoise {
    border-color: #32c5d2;
}
.panel-turquoise > .panel-heading + .panel-collapse > .panel-body {
    border-top-color: #32c5d2;
}

.panel-turquoise > .panel-heading {
    background-color: #eff3ff;
}

<div class="panel panel-turquoise">

Answer 4

bg-default

<div class="panel-group" id="accordion">
<div class="panel bg-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. Food truck quinoa nesciunt laborum eiusmod. Brunch 3 wolf moon tempor, sunt aliqua put a bird on it squid single-origin coffee nulla assumenda shoreditch et.
