What is the method for configuring body attributes in CSS with AngularJS?

Setting the background image of a page using CSS:

body {
    background: url(http://momentumbooks.com.au/wp-content/uploads/2013/06/space.jpg) no-repeat center center fixed;
    -webkit-background-size: cover;
    -moz-background-size: cover;
    -o-background-size: cover;
    background-size: cover;
    text-align: center;
}

Looking to read a property from a scoped variable in the controller:

$scope.image="http://momentumbooks.com.au/wp-content/uploads/2013/06/space.jpg"

How to set this CSS body attribute within the .html page with AngularJS? jQuery's .css() method is not working. Is there an alternative in AngularJS? http://docs.angularjs.org/guide/dev_guide.templates.css-styling doesn't provide clear instructions.

Here is a fiddle that I tried but it does not work:

http://jsfiddle.net/U3pVM/3015/

Fiddle code:

<body ng-style="getBodyStyle()">
</body>

$scope.getBodyStyle = function () {
    return {background: "url(http://momentumbooks.com.au/wp-content/uploads/2013/06/space.jpg) no-repeat center center fixed;"};
};

In order for your JSFiddle code to work properly, you need both an app and a controller. Currently, your JSFiddle is failing because it lacks a controller and $scope is never defined.

To create a $scope variable named $scope.bodyStyle in a controller, follow this example:

app.controller('MainCtrl', function($scope) {
 $scope.bodyStyle = {background: "url(http://momentumbooks.com.au/wp-content/uploads/2013/06/space.jpg) no-repeat center center fixed"};
});

You should then register the app and the controller in the HTML like so:

<html ng-app="plunker">

<body ng-controller="MainCtrl" ng-style="bodyStyle">
 Demo text
</body>

</html>

I have created a Plunkr to demonstrate the full app functionality, as JSFiddle can be challenging with Angular.

Angular requires more components working together compared to regular JS or JQuery, which can be overwhelming for beginners. I suggest starting with the AngularJS seed app to ease into it.

If you wish to access the background image from a $scope variable, you can implement it like this:

app.controller('MainCtrl', function($scope) {
  $scope.image="http://momentumbooks.com.au/wp-content/uploads/2013/06/space.jpg";
  $scope.bodyStyle = {background: "url(" + $scope.image + ") no-repeat center center fixed"};
});

Here is an example of how you could achieve this:

<header ng-style="getHeaderStyle()">

Additionally,

$scope.getHeaderStyle = function () {
    return {color: myColor};
};

My approach was to use an API call to retrieve the image URL and store it in the state under resolve:

resolve: {
   'image': ['$http', function($http) {
        return $http.get('/api/image');
    }]
}

The API responds with JSON:

res.json({url: 'someUrl'});

Then, I pass this URL to the controller and simply execute:

angular.element('body').css('background-image', 'url(\'' + image.data.url + '\')');

I find this method clean because it eliminates the need to inject $scope into the controller, which is now discouraged.
