Introduction:

"Hello and welcome back to our YouTube channel! In today's video, we will learn how to create a fullscreen toggle button for webpages using JavaScript. This button will allow users to enter and exit fullscreen mode with a single click. Let's get started!"

Step 1 - HTML Markup:

"First, let's set up the HTML markup. We need a button element with the ID 'fullscreen-button' to serve as our toggle button."

<button id="fullscreen-button">Toggle Fullscreen</button>

Step 2 - CSS Styling:

"To make our button visually appealing, we can add some CSS styling. Let's give the button some padding and a font size to make it more user-friendly."

<style>

    #fullscreen-button {

      padding: 10px;

      font-size: 16px;

    }

  </style>

Step 3 - JavaScript Code:

"Now, let's dive into the JavaScript code. We will write the logic to handle entering and exiting fullscreen mode using the requestFullscreen and exitFullscreen functions."

<script>

    // Function to enter fullscreen | code by anutrickz

   var isFullscreen=!1;function toggleFullscreen(){isFullscreen?document.exitFullscreen?.():document.documentElement.requestFullscreen?.(),isFullscreen=!isFullscreen}var button=document.getElementById("fullscreen-button");button.addEventListener("click",toggleFullscreen);

  </script>
