Adds support for CSS custom properties (variables) to your application

ember install ember-cli-custom-properties

• Uses modifiers to apply custom properties
• Maps component attributes to CSS custom properties
• Fast, lightweight implementation
• Only updates CSS custom properties when its bound component value changes
• Zero configuration design
• Production ready

Starting with Ember 2.17 or later, we switched to using modifiers to set custom properties on an element. This design decision makes it a lot easier to apply a custom property at any level of the application, including top-level templates.

Here is the new an improved way for setting a custom property. You just need to make sure the variables passed into the modifier is tracked.

<div {{custom-property "--background-image" backgroundImage}}></div>

The first parameter to the modifier is the custom property in from your CSS file. The second parameter is the value of the custom property.

You remove a CSS custom property value by simply setting its bound component property to null or undefined.

Happy Coding!
