Hamburger animated menu by using HTML and CSS only.

Posted By :Ravi Rose |29th April 2019

Introduction

Hamburger menu icons have become famous on many websites and web apps. A large menu can be displayed just by clicking the button. It is compact and due to its space saving nature, they have become the most popular UI element, especially on smaller screens. So if you are looking for new ways to animate those three lines into a neat X, check out the following Code. 

 

MARK UP :

This input type checkbox will give the toggle behavior, it will be hidden, but functional.

<input id="toggle" type="checkbox">

Any element that we want to modify when the checkbox state changes go here, being "sibling" of the checkbox element

The following label is tied to the checkbox, and it will contain the toggle "buttons"

<label class="toggle-container" for="toggle">
</label>
If the menu is shown, this will change to the 'X' icon, otherwise it will behave just as a clickable area behind the hamburger menu icon.
Now comes our Navigation menu
 
<nav class="nav">
  <a class="nav-item" href="">Home</a>
  <a class="nav-item" href="">Dashboard</a>
  <a class="nav-item" href="">Settings</a>
  <a class="nav-item" href="">Contact Us</a>
</nav>
 
CSS:
  /* Toggle functionality */
 
#toggle {
    position: absolute;
    left: -100%;
    top: -100%;
    opacity: 0;
}
 
label.toggle-container {
    display: inline !important;
}
 
#toggle:focus ~ .toggle-container .button-toggle {
    box-shadow: 0 0 0 0px rgba(12, 28, 38, 0.65), inset 0 0 0 24px rgba(12, 28, 38, 0.65);
}
 
/* Styles for the 'open' state, if the checkbox is checked*/
 
/* Any element you need to change the style if menu is open goes here, using the sibling selector (~) as follows
 
Making the "X" icon using `:before` and `:after` pseudo-elements */
 
#toggle:checked ~ .toggle-container .button-toggle {
    box-shadow: none;
    width: 23px;
    right: 10px;
}
 
#toggle:checked ~ .toggle-container .button-toggle:hover {
    box-shadow: none;
}
 
#toggle:checked ~ .toggle-container .button-toggle:before {
    transform: translateY(-50%) rotate(45deg) scale(1);
}
 
#toggle:checked ~ .toggle-container .button-toggle:after {
    transform: translateY(-50%) rotate(-45deg) scale(1);

}
 
#toggle:checked ~ .nav {
    margin-bottom: 100px;
    pointer-events: auto;
    transform: translate(0px, 50px);
}
 
/* Restoring nav items from "lines" in the menu icon */
 
#toggle:checked ~ .nav .nav-item {
    color: #fff;
    letter-spacing: 0;
    height: 40px;
    line-height: 40px;

    transition: 0.5s, opacity 0.1s;
    font-size: 32px;
    font-family: AvantGardeBookBT;
}
 
/* Setting delays for the nav items in open transition */
 
#toggle:checked ~ .nav .nav-item:nth-child(1) {
    transition-delay: 0.15s;
}
 
#toggle:checked ~ .nav .nav-item:nth-child(1):before {

}

.button-toggle {
    position: absolute;
    display: inline-block;
    width: 47px;
    height: 48px;
