This code creates an Animated Full Screen Hamburger Menu in CSS. It works by using CSS and HTML to create a responsive navigation menu that expands and collapses when clicking a button. This menu is helpful for improving website navigation on smaller screens.

You can use this code for your website to create a stylish and responsive full-screen hamburger menu. It enhances user experience on mobile devices by providing an easily accessible navigation menu.

How to Create an Animated Full-Screen Hamburger Menu in CSS

1. Start by creating the HTML structure for your menu. You can use the following code as a template:

<h1>Crafted Elegance:  Elevating Your Website with Animated Navigation Using Checked Pseudo Elements</h1>
<h2>We can achieve this toggle effect using javascript event listner without using checked pseudo class and just using a button instead.</h2>

<div class="navigation">
    <input type="checkbox" class="navigation__checkbox" id="navi-toggle">
    <label for="navi-toggle" class="navigation__button">
      <span class="navigation__icon">&nbsp;</span>
    </label>
    <div class="navigation__background"></div>
    <nav class="navigation__nav">
      <ul class="navigation__list">
        <li class="navigation__item"><a href="#" class="navigation__link">About</a></li>
        <li class="navigation__item"><a href="#" class="navigation__link">Home</a></li>
        <li class="navigation__item"><a href="#" class="navigation__link">Benefits</a></li>
        <li class="navigation__item"><a href="#" class="navigation__link">Plans</a></li>
      </ul>
    </nav>
  </div>

Replace the sample links with your navigation links inside the <nav> element.

2. Copy and paste the following CSS code into your project. This code contains the styles needed to create the animated hamburger menu. Make sure to include it within the <style> tags in your HTML file or link to an external CSS file.
