Adding CSS Classes to Your Components Based on Properties Edit Page
Problem
You want to add or remove CSS class names to your Ember Components based on properties of the component.
Solution
Add property names to the classNameBindings
property of subclassed components.
Discussion
You can apply classes based on properties of the component, or even by properties bound to data passed into the component.This is done by binding the class attribute using classNameBindings
.

classNameBindings: ['active'], active: true |
You can also set the class name based on a computed property.

classNameBindings: ['isActive'], isActive: function() { return 'active'; }.property('someAttribute') |
Another way would be to bind the class name to a bound property.

classNameBindings: ['isRelated:relative'], isRelatedBinding: "content.isRelated" // value resolves to boolean |
