Button Border Animation

Introduction

In this lab, we will explore how to create a button border animation on hover using CSS. By using the ::before and ::after pseudo-elements, we can add two boxes above and below the button and transition their width to 100% on hover. This lab will help you to enhance your CSS skills and add interactivity to your web pages.

Button Border Animation

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

To create a border animation on hover, you can use the ::before and ::after pseudo-elements to generate two boxes that are 24px wide and positioned above and below the box. Then, apply the :hover pseudo-class to increase the width of those elements to 100% on hover and animate the transition using transition.

Here's an example code snippet:

<button class="animated-border-button">Submit</button>

.animated-border-button {
  background-color: #263059;
  border: none;
  color: #ffffff;
  outline: none;
  padding: 12px 40px 10px;
  position: relative;
}

.animated-border-button::before,
.animated-border-button::after {
  border: 0 solid transparent;
  transition: all 0.3s;
  content: "";
  height: 0;
  position: absolute;
  width: 24px;
}

.animated-border-button::before {
  border-top: 2px solid #263059;
  right: 0;
  top: -4px;
}

.animated-border-button::after {
  border-bottom: 2px solid #263059;
  bottom: -4px;
  left: 0;
}

.animated-border-button:hover::before,
.animated-border-button:hover::after {
  width: 100%;
}
