设定.angular-cli.json

如下,设定font-awesome和primeng相关的css:

      "styles": [
        "styles.css",
        "../node_modules/primeng/resources/themes/omega/theme.css",
        "../node_modules/primeng/resources/primeng.min.css",
        "../node_modules/font-awesome/css/font-awesome.css"
      ],

修改HTML模板

修改app.component.html

[root@angular app]# cat app.component.html 
<!--The content below is only a placeholder and can be replaced.-->
<div style="text-align:center">
  <h1>
    Welcome to {
   
     {
   
     title}}!
  </h1>
</div>

<h3 class="first">Addons</h3>
<div class="ui-g ui-fluid">
    <div class="ui-g-12 ui-md-4">
        <div class="ui-inputgroup">
            <span class="ui-inputgroup-addon"><i class="fa fa-user"></i></span>
            <input type="text" pInputText placeholder="Username">

        <div class="ui-inputgroup">
            <span class="ui-inputgroup-addon">$</span>
            <input type="text" pInputText placeholder="Price">   
            <span class="ui-inputgroup-addon">.00</span>      
        </div>
