What is the usage of keyframes in css3
This attribute is closely related to the animation attribute.
Keyframes translated into Chinese means "key frames". If you have used flash, you should understand this better. Of course, if you don't know flash, there will be no problem.
Using the transition attribute can also achieve the transition animation effect, but it is slightly rough because it cannot control the animation process more finely. For example, it can only overall control the transition of a certain attribute within a specified time period, and The animation attribute can use @keyframes to divide the animation within the specified time period more finely.
Syntax structure:
@keyframes animationname {keyframes-selector {css-styles;}}Parameter analysis:
animationname: declares the name of the animation.
keyframes-selector: Used to divide the duration of animation, you can use percentage form, or you can use "from" and "to" forms. The forms "from" and "to" are equivalent to 0% and 100%. It is recommended to always use percentage form.
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;
animation:fadenum 5s infinite;
}
@keyframes fadenum{
100%{transform:rotate(360deg);}
}
</style>
</head>
<body>
<div></div>

Nodes are entities in the JavaScript DOM that represent HTML elements. They represent a specific element in the page and can be used to access and manipulate that element. Common node types include element nodes, text nodes, comment nodes, and document nodes. Through DOM methods such as getElementById(), you can access nodes and operate on them, including modifying properties, adding/removing child nodes, inserting/replacing nodes, and cloning nodes.
