In css, to achieve an animation that disappears after a few seconds, you need to use the animation property and the @ keyframes rule to achieve the effect that the picture disappears after a few seconds. With the @ keyframes rule, you can create an animation.

The principle of creating animation is to gradually change one set of CSS styles into another. You can change this CSS style many times during the animation process.

Specify the time when the change occurs as a percentage, or through the keywords "from" and "to", which is equivalent to 0 and 100%. 0% is the start time of the animation and the end time of 100% of the animation. For optimal browser support, you should always define 0% and 100% selectors.

The element disappearance style is controlled by using the opacity attribute.

Examples are as follows:

Document 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;}}
