How to Create a Toggle Button with a Push-In and Pop-Out Effect Using HTML and CSS?

Creating a Toggle Button in HTML and CSS

Question:

How can I create a toggle button in HTML using CSS that remains pushed in when clicked and pops out when clicked again?

Answer:

Implementing a pure CSS solution for a functional toggle button is challenging. An alternative approach is to utilize a checkbox styled using CSS and supplemented with JavaScript.

jQuery Implementation:

The recommended solution involves a simple jQuery function and two background images to denote the different button states. Here's an example:

<code class="javascript">$(document).ready(function() {
  $('a#button').click(function() {
    $(this).toggleClass("down");
  });
});</code>

<code class="css">a {
  background: #ccc;
  cursor: pointer;
  border-top: solid 2px #eaeaea;
  border-left: solid 2px #eaeaea;
  border-bottom: solid 2px #777;
  border-right: solid 2px #777;
  padding: 5px 5px;
}

a.down {
  background: #bbb;
  border-top: solid 2px #777;
  border-left: solid 2px #777;
  border-bottom: solid 2px #eaeaea;
  border-right: solid 2px #eaeaea;
}</code>

<code class="html"><script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a id="button" title="button">Press Me</a></code>
