<div class="panel-group" id="accordion">
  <div class="panel panel-default">
    <div class="panel-heading">
      <h4 class="panel-title">
      
      <a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion" href="#collapseOne">
          <i class="indicator glyphicon glyphicon-minus"></i>
          Collapsible Group Item #1
        </a>
      
        
      </h4>
    </div>
    <div id="collapseOne" class="panel-collapse collapse in">
      <div class="panel-body">

css:

.panel-heading .accordion-toggle:after {
    /* symbol for "opening" panels */
    font-family: 'Glyphicons Halflings';  /* essential for enabling glyphicon */
    content: "\e113";    /* adjust as needed, taken from bootstrap.css */
    float: right;        /* adjust as needed */
    color: black;         /* adjust as needed */

    /* symbol for "collapsed" panels */
    content: "\e114";    /* adjust as needed, taken from bootstrap.css */
}

.accordion-toggle:hover {
      text-decoration: none;
    }

js:

<script>

function toggleChevron(e) {
      $(e.target)
        .prev('.panel-heading')
        .find('i.indicator')
        .toggleClass('glyphicon-minus glyphicon-plus');
        $('#accordion','.panel-heading').css('background-color', 'green');
}
$('#accordion').on('hidden.bs.collapse', toggleChevron);
$('#accordion').on('shown.bs.collapse', toggleChevron);

</script>

Hi,

Add a class to the panel heading when you toggle the element and use that class in css to style the panel heading.

e.g. Use this JS:

<script>

function toggleChevron(e) {
      $(e.target)
        .prev('.panel-heading')
        .find('i.indicator')
        .toggleClass('glyphicon-minus glyphicon-plus');
        //$('#accordion .panel-heading').css('background-color', 'green');
				$('#accordion .panel-heading').removeClass('highlight');
				$(e.target).prev('.panel-heading').addClass('highlight');
}
$('#accordion').on('hidden.bs.collapse', toggleChevron);
$('#accordion').on('shown.bs.collapse', toggleChevron);

</script>

Then use this CSS:

#accordion .highlight {
	background:green;
	transition:background 2s ease;
}

Thanks a lot Paul its working fine,
I had forgot to mention in my above query that icons which I am using in accordion that should be white on click, I am confused that how I can use Bootstrap css code/Jquery for this when I click accordion to change the icon color to white…

Thanks
