How to achieve the scaling animation effect in css3
In css, you can use the animation attribute and @keyframes rules to achieve the animation effect of element scaling, through @keyframes rules, able to 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 the scaling effect of elements. The transform property applies a 2D or 3D transformation to an element. This property allows us to rotate, scale, move or tilt the element.
The example is as follows:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>css</title>
<style>
img{
animation:fadenum 5s ;
}
@keyframes fadenum{
100%{transform:scale(0.5,0.5);}
}
</style>
</head>
<body>
