css:

 .answer-wrapper {         display: none;     }      .arrow {       margin: 1em;     }      .arrow::before {       position: absolute;       content: '';       width: 0;       height: 0;       border: .5em solid transparent;       border-left-color: gray;       transform-origin: 0 50%;       transition: transform .25s;     }      .arrow.down::before {       transform: rotate(90deg);       transition: transform .25s;     }

javascript:

$(document)     .on('click','.row',function(){          $(this).find('.answer-wrapper').slidetoggle();     })      .on('click','.faq-expand',function(){         $('.answer-wrapper').slidedown();     })      .on('click','.faq-collapse',function(){         $('.answer-wrapper').slideup();     })  var arr = document.queryselector('.arrow'); arr.addeventlistener('click', function(event) {   event.target.classlist.toggle('down'); }); ;

here working fiddle javascript, css still needs bit of work:

jsfiddle

basically using wrong selectors jquery.

html:

<div class="container faq_wrapper">     <div class="row">         <div class="span10 offset1">             <p>                 &nbsp;</p>             <div class="faq-all-actions">                 <a class="faq-expand">expand all</a>&nbsp;&nbsp;|&nbsp;&nbsp;<a class="faq-collapse">collapse all</a></div>         </div>     </div>     <div class="row">         <div class="span10 offset1">             <div class="question-wrapper">                 <div class="arrows">                     &nbsp;</div>                 <div class="big-q">                     q</div>                 <div class="question">                     <div class="arrow"></div><h6>can try software before buy it?</h6></div>                 <div class="answer-wrapper">                     <div class="big-a">                         a</div>                     <div class="answer">                         yes! <a href="/trial">download free trial</a> , you&#39;ll have instant access features 30 days, absolutely free. don&#39;t require credit card details or commitment.</div>                 </div>             </div>             </div>     </div> </div>

jquery:

$(document).ready(function() {     .on('click','.row .question-wrapper',function(){          $(this).find('.answer-wrapper').slidetoggle();         $('.arrow').toggleclass('down');     })      .on('click','.faq-expand',function(){         $('.answer-wrapper').slidedown();         $('.arrow').addclass('down');     })      .on('click','.faq-collapse',function(){         $('.answer-wrapper').slideup();         $('.arrow').removeclass('down');     })  });
