Creating the HTML Structure

First, create a file named index.html with the default HTML boilerplate code for the fullscreen overlay navigation HTML code.

Include the Font Awesome CDN inside the head section for icons. Font Awesome is the best icon library and toolkit, and it is easy to use and used by millions of designers, developers, and content creators.

Now, create a div with the class name ‘container’. It holds two more divs, one with the class name ‘toggle’, which contains the Font Awesome bars icon, and the other with the class name ‘menu’, which includes the Font Awesome times icon and an unordered list for the nav links.

Copy and paste the following HTML code into the file named index.html:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <link rel="stylesheet" href="style.css">
    <!-- Font Awesome Link -->
    <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css">
    <title>Full Screen Navigation Menu - Coding Power</title>
</head>
<body>

    <div class="container">
        <div class="toggle">
            <span class="fa fa-bars" onclick="document.querySelector('.menu').classList.add('active')"></span>
        </div>
        <div class="menu">
            <span class="fa fa-times" onclick="document.querySelector('.menu').classList.remove('active')"></span>
            <ul>
                <li><a href="#">Home</a></li>
                <li><a href="#">Blog</a></li>
                <li><a href="#">About</a></li>
                <li><a href="#">Services</a></li>
                <li><a href="#">Contact us</a></li>
            </ul>
        </div>
    </div>
    
</body>
</html>

Styling with CSS

Create a new file named style.css and add a style link to the HTML head to link to the CSS file. If you miss that, then CSS will not work for any HTML class or element. Firstly, use the @import rule to import the Google Fonts library for the ‘Poppins’ font with different weights.

With the relative positioning, style the container div to take up the entire width and height of the viewport. The toggle span is styled to have absolute positioning, with a font size of 30 pixels, a line height of 35 pixels, a background of #333, and a border radius of 4 pixels.

Now, the menu div is styled to have an absolute positioning with a background of #8338ec, width and height of 100%, z index of 5, top of 0, left of -100%, and a transition of 0.5 seconds to set left as 0 when the active class is applied.

Then, style the menu span to have an absolute positioning with a font size of 30 pixels, a line height of 35 pixels, a background of #333, a border radius of 4 pixels, and a pointer cursor. Also, style the unordered list with an absolute positioning and no list style.

The list items have a block display with center-aligned text, a border radius of 15 pixels, appropriate margin and padding for extra spacing, and a transition of 0.2 seconds to change the background to tomato on hover. The a tag has a font size of 25 pixels with no text decor.

Copy and paste the following CSS code into the file named style.css:

@import url('https://fonts.googleapis.com/css2?family=Poppins:wght@300;400;500;600&display=swap');

*{
    margin: 0;
    padding: 0;
    box-sizing: border-box;
    font-family: 'Poppins', sans-serif;
}

.container{
    position: relative;
    width: 100%;
    height: 100vh;
}

.container .toggle span{
    position: absolute;
    top: 20px;
    left: 35px;
    font-size: 30px;
    line-height: 35px;
    padding: 6px 10px;
    color: white;
    background: #333;
    border-radius: 4px;
    cursor: pointer;
}

.container .menu{
    width: 100%;
    height: 100%;
    background: #8338ec;
    position: absolute;
    top: 0;
    left: -100%;
    z-index: 5;
    transition: 0.5s;
}

.container .menu.active{
    left: 0;
}

.container .menu span{
    position: absolute;
    top: 20px;
    right: 35px;
    font-size: 30px;
    line-height: 35px;
    padding: 6px 10px;
    color: white;
    background: #333;
    border-radius: 4px;
    cursor: pointer;
}

.container .menu ul{
    position: absolute;
    left: 50%;
    top: 50%;
    transform: translate(-50%,-50%);
    list-style: none;
}

.container .menu ul li{
    display: block;
    padding: 5px;
    margin-top: 20px;
    text-align: center;
    border-radius: 15px;
    transition: 0.2s;
}

.container .menu ul li:hover{
    background: tomato;
}

.container .menu ul li a{
    text-decoration: none;
    font-size: 25px;
    color: white;
}
