title: How to add function in toggle button
body: <p>I want to add some functionality on toggle button change. Currently it has no functionality in toggle change. I want a method that will be called on toggle change and do some work if it is off and if it is on. I want to show and hide some link under toggle change. I have attached the sample code (CSS and HTML). Please some one help me to write the syntax.</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>.switch {
    position: relative;
    display: inline-block;
    width: 60px;
    height: 34px;
  }
  
  .switch input {
    display: none;
  }
  
  .slider {
    position: absolute;
    cursor: pointer;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
    background-color: #ccc;
    -webkit-transition: .4s;
    transition: .4s;
  }
  
  .slider:before {
    position: absolute;
    content: "";
    height: 26px;
    width: 26px;
    left: 4px;
    bottom: 4px;
    background-color: white;
    -webkit-transition: .4s;
    transition: .4s;
  }
  
  input:checked+.slider {
    background-color: #2196F3;
  }
  
  input:focus+.slider {
    box-shadow: 0 0 1px #2196F3;
  }
  
  input:checked+.slider:before {
    -webkit-transform: translateX(26px);
    -ms-transform: translateX(26px);
    transform: translateX(26px);
  }
  
  
  /* Rounded sliders */
  
  .slider.round {
    border-radius: 34px;
  }
  
  .slider.round:before {
    border-radius: 50%;
