React
与其他框架类似， React 也需要一个入口点，例如 div#app 如此。
这是一个 React Hello World 案例，一定不要忘记在 script 标签添加 type="text/babel"：
<!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>react</title>
<style>
body {
font-family: sans-serif;
}
</style>
</head>
<body>
<div id="app"></div>

<script type="text/babel">
window.onload = (e) => {
const app = document.querySelector('#app');
const element = <h1>Hello World</h1>;
ReactDOM.render(element, app);
};
</script>
</body>
</html>
React 卡片组件
CDN 的方式使用 React 编写组件，模仿 堆糖(还差得远呢):
<!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>card</title>
<style>
body {
font-family: sans-serif;
}
div.container {
position: relative;
}
div.card {
float: left;
position: relative;
top: 0px;
left: 0px;
width: 200px;
border: 1px solid #dcdcdc;
border-radius: 1px;
margin: 10px;
}
div.card > img {
width: 190px;
margin: 5px;
}
div.card > p {
margin: 5px;
}
div.comment {
border-top: 1px solid #dcdcdc;
width: 90%;
}
div.comment > div.left {
display: inline-block;
width: 20%;
}
div.comment > div.right {
display: inline-block;
width: 78%;
}
div.comment > div > img {
margin: 8px 5px;
border-radius: 15px;
width: 20px;
height: 20px;
}
div.comment > div > p {
display: block;
line-height: 10px;
}
div.comment > div > p.comment {
color: #999;
font-size: 12px;
}
</style>
</head>
<body>
