Staggered Animation

Introduction

In this lab, we will learn how to create a staggered animation effect for a list of elements using CSS. We will use the opacity and transform properties to make the elements transparent and move them all the way to the right. Then, we will use transition-delay and the :checked pseudo-class selector to make the elements appear and slide into view in a staggered manner. By the end of this lab, you will be able to create visually appealing animations for your web pages.

index.html and style.css have already been provided in the VM.

This code creates a staggered animation for a list's elements. To do this:

Make the list elements transparent and move them all the way to the right by setting opacity: 0 and transform: translateX(100%).
Specify the same transition properties for list elements, except transition-delay.
Use inline styles to specify a value for --i for each list element. This will be used for transition-delay to create the stagger effect.
Use the :checked pseudo-class selector for the checkbox to style list elements. To make them appear and slide into view, set opacity to 1 and transform to translateX(0).

Here is the HTML and CSS code to achieve this effect:

<div class="container">
  <input type="checkbox" name="menu" id="menu" class="menu-toggler" />
  <label for="menu" class="menu-toggler-label">Menu</label>
  <ul class="stagger-menu">
    <li style="--i: 0">Home</li>
    <li style="--i: 1">Pricing</li>
    <li style="--i: 2">Account</li>
    <li style="--i: 3">Support</li>
    <li style="--i: 4">About</li>
  </ul>
</div>

.container {
  overflow-x: hidden;
  width: 100%;
}

.menu-toggler {
  display: none;
}

.menu-toggler-label {
  cursor: pointer;
  font-size: 20px;
  font-weight: bold;
}

.stagger-menu {
  list-style-type: none;
  margin: 16px 0;
  padding: 0;
}

.stagger-menu li {
  margin-bottom: 8px;
  font-size: 18px;
  opacity: 0;
  transform: translateX(100%);
  transition:
    opacity 0.3s cubic-bezier(0.75, -0.015, 0.565, 1.055),
    transform 0.3s cubic-bezier(0.75, -0.015, 0.565, 1.055);
}

.menu-toggler:checked ~ .stagger-menu li {
  opacity: 1;
  transform: translateX(0);
  transition-delay: calc(0.055s * var(--i));
}
