I have a tag:

```
<body ng-cloak class="foobar" ng-class="{'fixed-header': settings.isFixed}">

```

In another similar project I have a similar:

```
<body ng-cloak class="foobar" ng-class="routeClassName">

```

How can I apply both the `routeClassName` **and** the conditional class?

I have tried 

```
<body ng-cloak class="foobar" ng-class="{'routeClassName','fixed-header': settings.isFixed}">

```

and similar, but it throws an error. So I guess my syntax is off....
