Create an underline animation in CSS !

Hey fellow creators,

Let's learn how to create an easy but impactful underline animation in CSS so that your links look cooler!

If you prefer to watch the video version, it's right here :

1. The HTML Structure.

You only need to add a title to your body.

Enter fullscreen mode Exit fullscreen mode

2. Style the title.

Start by choosing whichever font you want for your body. I'll use Arial here.

body {
    font-family: Arial, Helvetica, sans-serif;
Enter fullscreen mode Exit fullscreen mode

Then, center the title in the middle of the page and style it a bit.

h1 {
    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
    font-size: 80px;
    cursor: pointer;
Enter fullscreen mode Exit fullscreen mode

3. Time to animate it!

The animation will run with the pseudo-element after.

    content: "";
    display: block;
    position: absolute;
    width: 100%;
    height: 3px;
    background: #000;
    transition: transform 0.2s ease-in-out;
    transform: scale(0);
Enter fullscreen mode Exit fullscreen mode

To trigger the animation, you need to hover over the title. So, once you do (with "h1:hover"), the animation will happen ("::after"), like so:

    transform: scale(1);
Enter fullscreen mode Exit fullscreen mode

(You can also replace "scale" with "scaleX", but it will only provoke a minor difference.)

You're done. And yes, it's that easy!

This is a nice animation to use on links for instance, because it will allow users to understand that it's a link.

You don't need to add display:inline to the h1 since it has position:absolute

Just kidding, it's a personal preference. But you can change your theme, font, etc. in your settings.

The more you know. 🌈
