How do I change the background-color of an accordion tab in Bootstrap?
提问by Kory Hershock
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.
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，它只会更改文本背后的颜色，而不是整个内容。
Here is a segment of my code:
这是我的一段代码：
<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">

You are probably changing the background-colorof the anchor tag if only the text's background is changing, instead, use the following CSS selector to change the background-colorof the panel-heading:
background-color如果仅更改文本的背景，您可能正在更改锚标记的 ，而是使用以下 CSS 选择器更改background-color的panel-heading：
.panel-default > .panel-heading {
background-color:#000;
}

You likely need to create your own custom contextual state class for the panel. Bootstrap comes with a bunch built in, but if you want something completely different you'll need to add one. This for example would create a new contextual state class for the panels called flashy:
您可能需要为面板创建自己的自定义上下文状态类。Bootstrap 内置了一堆，但是如果您想要完全不同的东西，则需要添加一个。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:
HTML代码：
<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>

Bootstrap has built-in styles:
Bootstrap 具有内置样式：
change
<div class="panel panel-default">
改变
<div class="panel panel-default">
to
<div class="panel panel-primary">
到
<div class="panel panel-primary">
all the other Bootstrap colours apply, so panel-successpanel-warningetc
see here: Bootstrap Contextual colors
所有其他 Bootstrap 颜色都适用，因此panel-successpanel-warning请参见此处：Bootstrap Contextual colours
any other colour would require you to write a class to supplement the bootstrap classes e.g.
任何其他颜色都需要您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">
<div class="panel panel-turquoise">
