While creating modern UI for checkbox or radio buttons, we usually convert them as a toggle or slide switch button using Javascript, so in this article, I have mentioned code example to create Javascript toggle button with HTML / CSS.

HTML and Javascript code would be as below

        <script type="text/javascript">
            function toggle(checkbox)
              if (checkbox.checked) {
      				// do this
              } else {
                // do that
                console.log('Not checked');
       <label class="switch">
        <input type="checkbox" onclick="toggle(this);">
        <div class="slider"></div>

and CSS as below

.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);

In CSS, we are hiding checkbox input inside .switch and adding slider toggle button, which will be visible, once slider is clicked, we are using CSS transform property for animation and changing background-color.

You will have output as below:
