CSS & JavaScript Popup Not Working -


why isn't javascript function triggering popup? i've tried .classlist style.visibility , neither triggers #filter div display.

<div class='lpicon' onclick="designfunction">     <img class='lpactionicon'  src='file:///users/homefolder/desktop/hyperspace%20website/images/launchpad/lp%20action%20icon-%20design.png'/> </div>  <div id='filter'> </div>

css: 

.lpicon {    height: 100px;    width: 50px;    margin-left: 14%;    margin-top: 8%;    float: left;   }  #filter {   visibility: hidden;   height: 100%;   width: 100%;   background-color: grey;   position: absolute;   opacity: .7;   top: 0px; }

javascript: 

function designfunction() {      document.getelementbyid("filter").classlist.remove("block");  }

i think need use designfunction() , need change css of filter div using block if not have provide more code because block present no where. can set slecting , using .css() making visible. see documentation more info.
