css and javascript to show figcaption of image when clicked -


i having trouble configuring javascript css when image clicked little caption bar appear icons in it. when hover on image caption bar appears want change usable users on tablets have touch , don't have hover feature.

view page

<figure>     <img width="158" height="158" alt="gravatar"               data-bind="attr:{src: gravatarurl}" />     <figcaption>          <a title="email" id="emailicon" class="icon-envelope icon-white"                     data-bind="attr:{'href':'mailto:' + email()}"></a>         <a title="profile" id="profileicon" class="icon-user icon-white"></a>     </figcaption> </figure>

css

figure, figcaption {     display: block; }   figure {     position:relative;     float:left;     margin:20px;     width:158px;     height:158px;     border:1px solid #333;     overflow:hidden;     background: #fff;     padding: 1px; }   figure figcaption {     position:absolute;     bottom:0;     left:0;     opacity: .75;     margin-bottom:-115px;            -webkit-transition: margin-bottom;     -webkit-transition-duration: 400ms;     -webkit-transition-timing-function: ease-out;     -moz-transition-property: margin-bottom;     -moz-transition-duration: 400ms;     -moz-transition-timing-function: ease-out;     -o-transition-property: margin-bottom;     -o-transition-duration: 400ms; }   figure.open figcaption {     margin-bottom:0px; }   figcaption {     width:160px;     height:25px;     background:#111;     color:#fff;     font-family: arial, helvetica, sans-serif; }

javascript not sure if there way css or not.

<script type="text/javascript">     (function ($) {         $.views.roster.getroster('@url');         $('figure').on('click', function (event) {             $(event.currenttarget).toggleclass('open');          });     })(jquery); </script>

it's great idea toggle class , leave visible elements css. 

$('figure').on('click', function (e) {     $(this).toggleclass('open');  });

in case, style figcaption way want , add:

figcaption { display: none; } .open figcaption { display: block; }

this way, when figcaption hidden default when click target , javascript adds class "open" figcaption visible. don't have have display block, other "none."
