css3的动画确实非常绚丽!浏览器兼容性很重要!。
分享两个小动画
<!doctype html><html lang="en"> <head> <meta charset="UTF-8"> <meta name="Generator" content="EditPlus®"> <meta name="Author" content=""> <meta name="Keywords" content=""> <meta name="Description" content=""> <title>C3动画</title> <style> /*****************/ #d1{width:50px;height:50px;background-color:green;float:left; border-radius:50%;} #d2{width:50px;height:50px;background-color:red;float:left; border-radius:50%;position:relative;} @-webkit-keyframes jump{ 0%{transform:rotate(0deg);opacity:1;} 25%{transform:rotate(-10deg);opacity:0.5;} 50%{transform:rotate(0deg);opacity:1;} 75%{transform:rotate(10deg);opacity:0.5;} 100%{transform:rotate(0deg);opacity:1;} } #d1{-webkit-animation:jump 0.3s linear infinite;} @-webkit-keyframes move{ 0%{left:10px;background-color:blue;} 50%{left:800px;background-color:yellow;} 100%{left:10px;background-color:red;} } #d2{-webkit-animation:move 5s linear infinite;} </style> </head> <body> <div id="d1"></div> <div id="d2"></div> </body></html>
效果如本博客首页那两个小圆圈!
需要注意的是:
1、在css里创建动画时候要处理兼容性
2、在调用的时候不单要处理兼容性> -webkit-animation: ; -moz-animation: ; -o-animation: ; animation: ;
还要注意animation:animation-name,animation-duration,animation-timing-function,animation-iteration-count
animation-name:是用来定义一个动画的名称
animation-duration是用来指定元素播放动画所持续的时间长,取值:为数值,单位为s (秒.)其默认值为“0”。
animation-timing-function:是指元素根据时间的推进来改变属性值的变换速率,说得简单点就是动画的播放方式.
具有以下六种变换方式:ease;ease-in;ease-in-out;linear;cubic- bezier。就是播放速度~
animation-iteration-count是用来指定元素播放动画的循环次数,其可以取值为数字,其默认值为“1”;infinite为无限次数循环。

The function of HTML is to define the structure and content of a web page, and its purpose is to provide a standardized way to display information. 1) HTML organizes various parts of the web page through tags and attributes, such as titles and paragraphs. 2) It supports the separation of content and performance and improves maintenance efficiency. 3) HTML is extensible, allowing custom tags to enhance SEO.

CSS-in-JS enhances style management flexibility but may increase file size. CSSHoudini allows direct operation of CSS rendering. 3.WebAssembly optimizes browser application performance but has a steep learning curve, and Serverless simplifies development but requires optimization of cold start problems.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
