本文介绍如何通过安装Polymer并利用Bower组件管理工具来创建第一个自定义Web组件。示例中详细展示了如何设置HTML文件以引入必要的Polymer库，并通过具体的`hello-world.html`实例讲解了自定义元素的定义和使用方法。

install Polymer and explore creating our first custom element:

 bower install polymer

index.html:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Polymer</title>
    <script src="bower_components/webcomponentsjs/webcomponents-lite.js"></script>
    <link rel="import" href="bower_components/polymer/polymer.html">
    <link rel="import" href="./hello-world.html">
</head>
<body>
<hello-world name="ZTW"></hello-world>
</body>
</html>

include webcomponents-list.js file
import polymer.html file
import our compoment hello-world.html file

hello-world.html:

<dom-module id="hello-world">
    <template>
        <input type="text" value="{{name::keyup}}"> <!-- {{}} two way data binding, ::bind to event -->
        <h1>Hello, [[name]]</h1> <!-- [[]] one way data binding -->
    </template>
    <script>
        Polymer({
            is: "hello-world"  // string match the tag
        })
    </script>
</dom-module>
