Toggle buttons are basically on/off buttons. A button can be switched from on to off state and vice-versa. This process is called toggling.
Examples of toggle button: 
 

  • The buttons on our switchboards are the best example of toggle buttons.
  • Some of the buttons on our phones- the torch button, the mobile data button, the wifi button, flight mode, Bluetooth button can be either on or off. These are all toggle buttons.

Approach: 
Now let’s see how to design these buttons in HTML with the help of Bootstrap.
Example 1: The default toggle button 
Code in HTML (Using Bootstrap): 
 

html




<div class="toggle">
    <div class="custom-control custom-switch">
      <input type="checkbox"
             class="custom-control-input"
             id="toggleSwitches">
      <label class="custom-control-label"
             for="toggleSwitches">
        TOGGLE</label>
    </div>
</div>


Style using CSS: 
 

html




<style>
        .toggle,
           {
           margin-top: 100px;
            font-size: 20px;
           }
           h1{
                color: green;
                font-size: 30px;
            }
             
</style>


Complete Code: 
 

html




<!DOCTYPE html>
<html>
    <head>
        <!-- Latest compiled and minified CSS -->
        <link rel="stylesheet"
              href=
 
        <!-- jQuery library -->
        <script src=
       </script>
 
        <!-- Popper JS -->
        <script src=
      </script>
 
        <!-- Latest compiled JavaScript -->
        <script src=
      </script>
 
        <meta name="viewport"
              content="width=device-width,
                       initial-scale=1" />
 
        <link rel="stylesheet"
              type="text/css"
              href="style.css" />
 
        <link href=
              rel="stylesheet" />
 
        <link href=
"https://fonts.googleapis.com/css2?family=Lato:ital, wght@0, 100;0, 300;0, 400;1, 300&display=swap"
              rel="stylesheet" />
        <script src=
                type="text/javascript"></script>
        <link href=
              rel="stylesheet"
              type="text/css" />
        <link rel="stylesheet"
              type="text/css"
              href="css/lightbox.min.css" />
        <script type="text/javascript"
                src="js/lightbox-plus-jquery.min.js">
      </script>
 
        <title>Buttons</title>
 
        <h1>GeeksforGeeks</h1>
 
        <style>
            .toggle {
                margin-top: 100px;
                font-size: 20px;
            }
            h1 {
                color: green;
                font-size: 30px;
            }
        </style>
    </head>
 
    <body>
        <div class="toggle">
            <div class="custom-control custom-switch">
                <input type="checkbox"
                       class="custom-control-input"
                       id="toggleSwitches" />
                <label class="custom-control-label"
                       for="toggleSwitches">
                  TOGGLE
              </label>
            </div>
        </div>
    </body>
</html>


Output: 
 

 

The switches use a custom-switch class to change it into toggle switches. 
Slight modifications can be done in the code to get desired results
Example 2: The toggle switches can also be given a checked attribute. If it is done so then the toggle button will always be pre-selected when the page loads. 
The checked attribute is a boolean attribute.
Code snippet: 
 

html




<div class="toggle">
    <div class="custom-control custom-switch">
        <input type="checkbox"
               class="custom-control-input"
               id="toggleSwitches"
               checked />
        <label class="custom-control-label"
               for="toggleSwitches">
          CHECKED TOGGLE BUTTON
      </label>
    </div>
</div>


Output: 
 

Example 3: We can also add the disabled attribute to the toggle button . If this is done then the switch can never be used and clicked.
Code snippet: 
 

html




<div class="toggle">
    <div class="custom-control custom-switch">
        <input type="checkbox"
               class="custom-control-input"
               id="toggleSwitches"
               disabled />
        <label class="custom-control-label"
               for="toggleSwitches">
          DISABLED TOGGLE BUTTON</label>
    </div>
</div>


Output:
