How to achieve the effect of the image disappearing after appearing for one second in css

In css, you can use the animation attribute and @keyframes rule to achieve the effect of the image appearing for one second. The effect disappears after seconds. With 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 image 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>
        img{
            opacity:0;
            animation:fadenum 3s;
        }
        @keyframes fadenum{
          0%{opacity:1;}
          99%{opacity:1;}
          100%{opacity:0;}
}
    </style>
</head>
<body>
    <img src="1118.02.png" alt="">
