In HTML5, the code for the 3D rotation animation effect is "element {animation: name time}@keyframes name {100%{transform:rotate3d(x,y,z,rotation angle);}}"; The animation attribute is used to specify the animation properties of the element.
The operating environment of this tutorial: Windows 10 system, HTML5 version, Dell G3 computer.
You can use the animation attribute and the @keyframes rule to achieve the animation effect of element scaling. Through the @keyframes rule, animation can be created.
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 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:100px;
height:100px;
background-color:pink;
overflow:hidden;
animation:fadenum 5s ;
}
@keyframes fadenum{
100%{transform:rotateY(70deg);}
}
</style>
</head>
