Here is a solution that creates a section that is expandable using somewhat material design, bootstrap 4.5/5 alpha and entirely non-javascript.

Style for head section

<style>
[data-toggle="collapse"] .fa:before {
    content: "\f077";
}

[data-toggle="collapse"].collapsed .fa:before {
    content: "\f078";
}
</style>

Body html

<div class="pt-3 pb-3" style="border-top: 1px solid #eeeeee; border-bottom: 1px solid #eeeeee; cursor: pointer;">
<a href="#expandId" class="text-dark float-right collapsed" data-toggle="collapse" role="button" aria-expanded="false" aria-controls="expandId">
    <i class="fa" aria-hidden="false"></i>
</a>
<a href="#expandId" class="text-dark collapsed" data-toggle="collapse" role="button" aria-expanded="false" aria-controls="expandId">Expand Header</a>
<div class="collapse" id="expandId">
    CONTENT GOES IN HERE
</div>

RobSadler   RE Martin Wickman s CSS only version     You can get around that problem by putting accordion-caret on the anchor tag and giving it a collapsed class by default   Like so    lt div class  accordion-group  gt   lt div class  accordion-heading  gt       lt a class  accordion-toggle accordion-caret collapsed  data-toggle  collapse  href   collapseOne  gt           lt strong gt Header lt  strong gt       lt  a gt   lt  div gt   lt div id  collapseOne  class  accordion-body collapse in  gt       lt div class  accordion-inner  gt          Content      lt  div gt   lt  div gt      That worked for me

The most readable CSS-only solution would probably be to use the aria-expanded attribute  Remember that you ll need to add aria-expanded  false  to all collapse-elements as this is not set on load  only on first click    The HTML    lt h2 data-toggle  collapse  href   collapseId  aria-expanded  false  gt       lt span class  glyphicon glyphicon-chevron-right  gt  lt  span gt       lt span class  glyphicon glyphicon-chevron-down  gt  lt  span gt  Title  lt  h2 gt    The CSS   h2 aria-expanded  false   span glyphicon-chevron-down  h2 aria-expanded  true   span glyphicon-chevron-right       display  none     h2 aria-expanded  true   span glyphicon-chevron-down  h2 aria-expanded  false   span glyphicon-chevron-right       display  inline      Works with Bootstrap 3 x

If anyone is interested this is how you do it with BS3 since they changed the event names       collapse   on  show bs collapse   function      var i     this  parent   find  i     i toggleClass  fa-caret-right fa-caret-down       on  hide bs collapse   function      var i     this  parent   find  i     i toggleClass  fa-caret-down fa-caret-right          You simply change the class names in the example to the ones you use in your case

This has been answered by numerous ways but what I came up with was the simplest and easiest for me with Bootstrap 3 and font awesome  I just did     a toggler   on  click   function        i   this  toggleClass  fa-caret-up         This just toggles the CSS class of the icon I want to show  I add the class toggler to the item I want to apply this to  This can be added onto any item you want to toggle an icon

Added to  muffls answer so that this works with all twitter bootstrap collapse and makes the change to the arrow before the animatation starts       collapse   on  show   function          this  parent   find   icon-chevron-left   removeClass  icon-chevron-left   addClass  icon-chevron-down       on  hide   function          this  parent   find   icon-chevron-down   removeClass  icon-chevron-down   addClass  icon-chevron-left          Depending on your HTML structure you may need to modify the parent

For a CSS-only  and icon-free  solution using Bootstrap 3 I had to do a bit of fiddling based on Martin Wickman s answer above    I didn t use the accordion-  notation because it s done with panels in BS3    Also  I had to include in the initial HTML aria-expanded  true  on the item that s open at page load    Here is the CSS I used    accordion-toggle hover   text-decoration  none     accordion-toggle hover span   accordion-toggle hover strong   text-decoration  underline     accordion-toggle before   font-size  25px     accordion-toggle data-toggle  collapse   before   content       margin-right  0px     accordion-toggle aria-expanded  true   before   content   -   margin-right  0px      Here is my sanitized HTML    lt div id  acc1  gt           lt div class  panel panel-default  gt           lt div class  panel-heading  gt               lt span class  panel-title  gt                   lt a class  accordion-toggle  data-toggle  collapse  aria-expanded  true  data-parent   acc1  href   acc1-1  gt Title 1                      lt  a gt               lt  span gt           lt  div gt           lt div id    acc1-1    class  panel-collapse collapse in  gt               lt div class  panel-body  gt                  Text 1              lt  div gt           lt  div gt       lt  div gt       lt div class  panel panel-default  gt           lt div class  panel-heading  gt               lt span class  panel-title  gt                   lt a class  accordion-toggle  data-toggle  collapse  data-parent   acc1    href     acc1-2    gt Title 2                      lt  a gt               lt  span gt           lt  div gt           lt div id    acc1-2    class  panel-collapse collapse  gt               lt div class  panel-body  gt                  Text 2                                lt  div gt           lt  div gt       lt  div gt   lt  div gt

Shortest possible answer   HTML   lt a data-toggle  collapse  data-parent   panel-quote-group  href   collapseQuote  gt       lt span class  toggle-icon glyphicon glyphicon-collapse-up  gt  lt  span gt   lt  a gt    JS    lt script type  text javascript  gt     function              a data-toggle  collapse     click function             this  find  span toggle-icon   toggleClass  glyphicon-collapse-up glyphicon-collapse-down                  lt  script gt    And of course  you can use anything for a selector instead of anchor tag a and you can also use specific selector instead of this if your icon lies outside your clicked element

This is how I do it without any js    I used the icon glyphicon-triangle-right but it works with any other icon  what it does is that it applies a 90 degrees rotation to the icon when the panel is open or not  I m using Bootstrap 3 3 5 for this one   CSS Code  h4 panel-title a       display  block     h4 panel-title a collapsed  glyphicon-triangle-right           color   ada9a9  important          transform  rotate 0deg     h4 panel-title a  glyphicon-triangle-right           color   515e64  important          transform  rotate 90deg       This is the HTML structure taken from the Bootstrap example   lt div class  panel-group  id  accordion  role  tablist  aria-multiselectable  true  gt                               lt div class  panel panel-default  gt                                   lt div class  panel-heading  role  tab  id  headingOne  gt                                       lt h4 class  panel-title  gt                                           lt a role  button  data-toggle  collapse  data-parent   accordion  href   collapseOne  aria-expanded  true  aria-controls  collapseOne  gt                                              Proven Expertise                                              lt span class  glyphicon glyphicon-triangle-right pull-right  aria-hidden  true  gt  lt  span gt                                           lt  a gt                                       lt  h4 gt                                   lt  div gt                                   lt div id  collapseOne  class  panel-collapse collapse in  role  tabpanel  aria-labelledby  headingOne  gt                                       lt div class  panel-body  gt                                          Anim pariatur cliche reprehenderit  enim eiusmod high life accusamus terry richardson ad squid  3 wolf moon officia aute  non cupidatat skateboard dolor brunch  Food truck quinoa nesciunt laborum eiusmod  Brunch 3 wolf moon tempor  sunt aliqua put a bird on it squid single-origin coffee nulla assumenda shoreditch et  Nihil anim keffiyeh helvetica  craft beer labore wes anderson cred nesciunt sapiente ea proident  Ad vegan excepteur butcher vice lomo  Leggings occaecat craft beer farm-to-table  raw denim aesthetic synth nesciunt you probably haven t heard of them accusamus labore sustainable VHS                                       lt  div gt                                   lt  div gt                               lt  div gt                            lt  div gt
