Question

当我点击可折叠面板时，您会看到标签颜色从黄色变为深绿色，我希望能够将字体颜色从红色更改为白色，我认为它会像它一样简单是改变背景，但经过各种尝试，我只是没有线索，任何人都可以帮忙吗？

$(document).ready(function() {
  // hide all div containers
  $('#collapsible-panels div').hide();
  // append click event to the a element
  $('#collapsible-panels a').click(function(e) {
    // slide down the corresponding div if hidden, or slide up if shown
    $(this).parent().next('#collapsible-panels div').slideToggle('slow');
    // set the current item as active
    $(this).parent().toggleClass('active');
    e.preventDefault();
  });
});

body {
  margin: 0px;
  padding: 0px;
}
#collapsible-panels {
  margin: 0px;
  padding: 0px;
  margin-top: 25px;
  -moz-box-shadow: 2px 2px 5px #333;
  -webkit-box-shadow: 2px 2px 5px #999;
  color: rgba(102, 102, 102, 1);
}
#collapsible-panels h2 {

Answer 1

只需添加一点CSS：

#collapsible-panels h2 a{
    color:#ffffff; /*white*/
}

#collapsible-panels h2.active a{
    color:#ff0000; /*red*/
}

Answer 2

简单地改变：

#collapsible-panels h2 a {
    padding: 0 0 0 35px;
    text-decoration: none;
    color: rgba(255,0,0,1);
}

与

#collapsible-panels h2 a {
    padding: 0 0 0 35px;
    text-decoration: none;
    color: #fff;
}
#collapsible-panels h2.active a {
    color: rgba(255,0,0,1);
}

就是这样。

可以通过更改样式来实现它，或者您可以按如下方式为标题切换类，即h2

＆＃13;

$(document).ready(function() {

  // hide all div containers
  $('#collapsible-panels div').hide();
  // append click event to the a element
  $('#collapsible-panels a').click(function(e) {
    // slide down the corresponding div if hidden, or slide up if shown
    $(this).parent().next('#collapsible-panels div').slideToggle('slow');
    // set the current item as active
    $(this).parent().find('a').toggleClass('active1');
    $(this).parent().toggleClass('active');
    e.preventDefault();
  });
});
