Hover Underline Animation

Introduction

In this lab, we will learn how to create a hover underline animation using CSS. This effect can be used to add visual interest to text and improve the user experience of a website. By following the steps outlined in this lab, you will gain a better understanding of how to use CSS to create dynamic and engaging web content.

Hover Underline Animation

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

To create an animated underline effect when the user hovers over the text, follow these steps:

1. Use display: inline-block to make the underline span just the width of the text content.
2. Use the ::after pseudo-element with width: 100% and position: absolute to place it below the content.
3. Use transform: scaleX(0) to initially hide the pseudo-element.
4. Use the :hover pseudo-class selector to apply transform: scaleX(1) and display the pseudo-element on hover.
5. Animate transform using transform-origin: left and an appropriate transition.
6. Remove the transform-origin property to make the transform originate from the center of the element.

Here is an example HTML code to apply the effect to a text element:

<p class="hover-underline-animation">Hover this text to see the effect!</p>

And here is the corresponding CSS code:

.hover-underline-animation {
  display: inline-block;
  position: relative;
  color: #0087ca;
}

.hover-underline-animation::after {
  content: "";
  position: absolute;
  width: 100%;
  transform: scaleX(0);
  height: 2px;
  bottom: 0;
  left: 0;
  background-color: #0087ca;
  transform-origin: bottom right;
  transition: transform 0.25s ease-out;
}

.hover-underline-animation:hover::after {
  transform: scaleX(1);
  transform-origin: bottom left;
}
