I have created Modal using Salesforce Lightning Design System but it is not showing modal when i click the button. When i click the button it is not adding the style class using jquery.

My Problem is it is not adding the style class using java script button when i click on the button.

Following is my code.

<apex:page standardController="Account" extensions="ActivityDetailExtension" standardStylesheets="false" sidebar="false">
   <apex:stylesheet value="{!URLFOR($Resource.SLDS0105, '/assets/styles/salesforce-lightning-design-system-vf.css')}"/>
      .table-border {margin-top:20px;}
      .table-border tr td {border: 1px solid #d8dde6;}
      .table-border tr th {border: 1px solid #d8dde6;}
      .sub-goal {margin-left:50px;}
   <script src="https://code.jquery.com/jquery-1.10.1.min.js" type="text/javascript"></script>
      j$ = jQuery.noConflict();


      //Modal Open
      function openModal(){
        alert('classes are added successfully');

      //Modal Close
      function closeModal(){
   <div class="slds">
      <apex:form >
         <apex:commandButton onclick="openModal();" reRender="Modal" styleClass="slds-button slds-button--brand" value="Create New Sub-Goal" />
         <apex:outputPanel id="Modal">
            <div id="Modal" role="dialog" tabindex="-1" aria-labelledby="header43" class="slds-modal">
               <div class="slds-modal__container">
                  <div class="slds-modal__header">
                     <button class="slds-button slds-modal__close slds-button--icon-inverse" title="Close">
                        <svg class="slds-button__icon slds-button__icon--large" aria-hidden="true">
                           <!-- <use xlink:href="/assets/icons/utility-sprite/svg/symbols.svg#close"></use>-->
                        <span class="slds-assistive-text">Close</span>
                     <h2 id="header43" class="slds-text-heading--medium">Modal Header</h2>
                  <div class="slds-modal__content slds-p-around--medium">

  • One problem is mismatching case: j$('#modal') in the JavaScript and id="Modal" in the HTML.

  • @Ketih C removed the id from that div it will take j$('#modal') from class for that div. Commented Jan 28, 2017 at 9:39
