How to realize the animation that disappears after a few seconds in css3
In css, if you want to realize the animation that disappears after a few seconds, you need to use the animation attribute and the @keyframes rule to achieve the effect of the image appearing for a few seconds and then disappearing. Through the @keyframes rule, you can create animations.
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.
Specify the time when the change occurs as a percentage, or through the keywords "from" and "to", which are equivalent to 0% and 100%. 0% is the start time of the animation, 100% is the end time of the animation. For best browser support, you should always define 0% and 100% selectors.
Control the element disappearing style by using the opacity attribute.
The example is as follows:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
<style>
div{
width:150px;
height:100px;
opacity:0;
background-color:red;
animation-name:fadenum;
animation-duration:3s;
}
@keyframes fadenum{
0%{opacity:1;}
99%{opacity:1;}
100%{opacity:0;}
}
</style>
</head>
<body>
<div></div>
</body>
</html>Output result:
