In this article, we will learn to set the width of the border-bottom animate using CSS.
Approach: The border-bottom-width is the width of the bottom border, and we want to animate its width. We will use the animation property of the CSS. It takes three values
- The first is the name of the animation which is a keyframe name that we want to bind with.
Syntax:
@keyframe myFun
{
100%{
border-bottom-width: 25px;
}
}- The second is the time for which it animates.
- And the last one is the number of times we want to animate.
Syntax:
animation: animation_name animation_duration animation_count
Example: In this example, we will animate the bottom border.
HTML
<!DOCTYPE html><html>
<head>
<style>
.gfg {
width: 300px;
height: 200px;
border: solid 1px green;
color: green;
font-size: 30px;
margin-left: 20%;
animation: myFun 5s infinite;
}
@keyframes myFun {
100% {
border-bottom-width: 25px;
}
}
</style>
</head>
<body>
<div class="gfg">GeeksforGeeks</div>
</body>
</html>
|
Output:
