标签: html css twitter-bootstrap accordion collapse

我用Bootstrap创建了一个手风琴链接,我希望手风琴关闭时有一个“Plus”标志,当arcordon打开时我想有一个标识“Less”。这是我的HTML代码:

<div class="panel-group" id="accordion">
  <div class="panel panel-default">
    <div class="panel-heading">
      <a data-toggle="collapse" data-parent="#accordion" href="#collapse1">
        <h4 class="panel-title">
        <i class="fa fa-object-group fa-lg"></i> Ses contenus <span class="badge">12</span>
        <div class="panel-button"><i class="fa fa-minus-circle fa-lg"></i></div>
        </h4>
      </a>
    </div>
    <div id="collapse1" class="panel-collapse collapse">
      <div class="panel-body"><dd>{{ drupal_view('profil_page_contenu_utilisateur', 'block_1') }}</dd></div>
    </div>
  </div>
</div>

这是css,但不起作用:

body.path-profile .field--name-dynamic-block-fieldprofile-profil-page-contenu-utilisateur .panel-button div.collapse > a i:before {
    content: '\f055';
}

body.path-profile .field--name-dynamic-block-fieldprofile-profil-page-contenu-utilisateur .panel-button div.collapse > a[aria-expanded=true] i:before {
    content: '\f056';
}

Bootstrap使用它自己的Jquery进行折叠。

它也更适合你使用Jquery。
