Bootstrap 3 手风琴样式打开/关闭 [英] Bootstrap 3 accordion styling on open/closed

问题描述

试图对 bs3 手风琴进行风格化...我在标题和正文中添加了一个图像.我设法在关闭时设置黑色标题文本，在悬停和/或打开时设置蓝色文本.

如何在悬停和/或打开时更改面板标题"的背景颜色?我已经尝试了很多事情，但没有结果.通过添加/删除样式，这将成为仅 jquery 的解决方案吗?

<div class="panel-heading"><h4 class="panel-title"><a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion1" href="#accordion1_2">1. 这里有一些标题</a>
<div id="accordion1_2" class="panel-collapse collapse"><div class="panel-body">示例条目文本在此处

.面板常见问题{边框颜色:#dddddd；}.panel-faq .panel-heading {颜色:#333333；背景:#f5f5f5 url('/assets/img/faq-question.png') 不重复 10px 中心；左边距:45px；边框颜色:#dddddd；}.panel-default >.panel-heading + .panel-collapse .panel-body {边框顶部颜色:#dddddd；}.panel-default >.panel-footer + .panel-collapse .panel-body {边框底部颜色:#dddddd；}.panel-faq .panel-body {背景: url('/assets/img/faq-answer.png') 不重复 40px 20px;左边距:75px；}.panel-faq .accordion-toggle, .panel-faq a.accordion-toggle:hover{颜色:#428bca；文字装饰:无；}.panel-faq .accordion-toggle.collapsed {颜色:#333333；}

解决方案

由于我无法在 css 中做任何事情，所以我继续使用了一些 jquery.对于任何感兴趣的人，您可以向整个 div 添加/删除活动类，然后以这种方式应用样式.

 $('.panel-faq').on('show.bs.collapse', function () {$(this).addClass('active');});$('.panel-faq').on('hide.bs.collapse', function () {$(this).removeClass('active');});

Trying to stylize bs3 accordions... I had added an image to the title and the body. I have managed to set black title text on close and blue text on hover and/or open.

How can I change the background color of 'panel-heading' on hover and/or open? I have tried quite a few things with no results. Is this going to be a jquery only solution by adding/removing the styles?

<div class="panel panel-faq">
    <div class="panel-heading">
        <h4 class="panel-title">
            <a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion1" href="#accordion1_2">
                1. Some title goes here
            </a>
        </h4>
    </div>
    <div id="accordion1_2" class="panel-collapse collapse">
        <div class="panel-body">
                sample entry text goes here
        </div>
    </div>
</div>


.panel-faq{
    border-color: #dddddd;
}
.panel-faq .panel-heading {
    color: #333333;
    background:#f5f5f5 url('/assets/img/faq-question.png') no-repeat 10px center;
    padding-left: 45px;
    border-color: #dddddd;
}

.panel-default > .panel-heading + .panel-collapse .panel-body {
  border-top-color: #dddddd;
}

.panel-default > .panel-footer + .panel-collapse .panel-body {
  border-bottom-color: #dddddd;
}

.panel-faq .panel-body {
    background: url('/assets/img/faq-answer.png') no-repeat 40px 20px;
    padding-left: 75px;
}

.panel-faq .accordion-toggle, .panel-faq a.accordion-toggle:hover{
    color:#428bca;
    text-decoration:none;
}

.panel-faq .accordion-toggle.collapsed {
    color:#333333;
}

解决方案

Since I was unable to do anything in css only I went ahead and some jquery. For anyone interested you can add/remove an active class to the entire div then apply styling that way.

    $('.panel-faq').on('show.bs.collapse', function () {
         $(this).addClass('active');
    });

    $('.panel-faq').on('hide.bs.collapse', function () {
         $(this).removeClass('active');
    });
