The principle of creating animation is to gradually change one set of CSS styles into another set of styles.
You can change this set of CSS styles multiple times during the animation process.
Specify the time when the change occurs as a percentage, or through the keywords "from" and "to", which are equivalent to 0% and 100%.

For best browser support, you should always define 0% and 100% selectors.
Examples are as follows:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>123</title>
<style>
div
{
width: 80px;
height: 50px;
background:pink;
border:1px solid #000;
border-radius:50%;
}
div:hover
{
animation:fadenum 5s;
}
@keyframes fadenum{
100%{border-radius:0;}
}
}
</style>
</head>
