How to write the up and down movement of css elements
In css, you can use the animation attribute and @keyframes rules to achieve the animation effect of the element fading. , 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.
There is also a transform attribute used to set up and down motion.
The example is as follows:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>css</title>
<style>
img{
animation:fadenum 5s ;
}
@keyframes fadenum{
50%{transform:translateY(80px);}
}
</style>
</head>
