ionic头部bar-header，设置样式bar-balanced
2、实现源码
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="initial-scale=1.0, maximum-scale=1.0, user-scalable=no" />
<title>ionic之样式bar-balanced</title>
<link rel="stylesheet" href="../css/ionic.css" />
<script type="text/javascript" src="../js/ionic.bundle.js" ></script>
<script>
var app = angular.module("balancedApp",["ionic"]);
app.controller("balancedController",function($scope){
$scope.balanced = "替换";
});
</script>
</head>
<body ng-app="balancedApp" ng-controller="balancedController">
<p class="bar bar-header bar-balanced">
<label class="title">{{balanced}}</label>
</p>
</body>
</html>
