CSS is used to create beautiful and engaging border animations, which add movement and interest to a web page. To create border animation, we will first need to define a border for the element we want to animate, then we’ll use CSS transitions and animations to add movement to the border.
Border animations can be used to create hover effects on buttons, links, and other interactive elements. They can also be used to create loading animations that show progress while a page or element is loading. We can also use border animations on call-to-action buttons to make them more noticeable.
we will create a hover effect that animates the border of an element when a user hovers over it.
创建一个HTML文档，并将标题定义为"Hover Effect Border Animation"。
Add a pulsing animation to the border with an infinite duration and ease-in-out timing. 当鼠标悬停在盒子上时，将边框从红色渐变为绿色再到蓝色，并禁用脉动动画
Define the pulsing animation with a keyframe that changes the border color from red to green to blue. 在HTML文档的body中添加一个带有box类的div元素
Save and view the HTML file in a web browser to see the hover effect border animation.
<!DOCTYPE html>

/* Set up the body with flexbox to center the box */

/* When the box is hovered, change the border to a gradient and disable the pulsing animation */
.box:hover {
border-image: linear-gradient(to right, #f00, #0f0, #00f);
border-image-slice: 1;

}
/* Define the pulsing animation */
@keyframes border-pulse {

border-color: #f00;

50% {
border-color: #0f0;

100% {
border-color: #00f;
}
}
</style>

<body>
<!-- Add the box element to the HTML -->
<div class="box">

Here, we will create a loading animation by animating the border of the loading icon.
