Polymerjs app布局

应用程序布局元素由工具栏, 抽屉和标题等组件组成。这些仅用于标记即可用于构建高质量的响应式布局。下表列出了一些元素。

例：

在命令提示符处使用以下命令, 以使用应用程序布局元素移至项目目录。

bower install PolymerElements/app-layout --save

它将在bower-component文件夹中安装app-layout元素。然后, 你可以使用index.html文件中的<link>标记导入文件。

<link rel = "import" href = "/bower_components/app-layout/app-layout.html">
<base href = "https://user-content-dot-custom-elements.appspot.com/PolymerElements/app-layout/v1.0.1/app-layout/">
<script src = "../webcomponentsjs/webcomponents-lite.min.js"></script>
<link rel = "import" href = "app-header/app-header.html">
<link rel = "import" href = "app-toolbar/app-toolbar.html">
<link rel = "import" href = "app-box/app-box.html">
<link rel = "import" href = "demo/sample-content.html">
<link rel = "import" href = "../iron-icons/iron-icons.html">

<style is = "custom-style">
   html, body {

   paper-icon-button + [main-title] {

   paper-progress {

      width: 100%;
      --paper-progress-active-color: rgba(255, 255, 255, 0.5);
      --paper-progress-container-color: transparent;

   app-header {
