ember-css-vars

ember-css-vars is an Ember.js element modifier that provides a clean, declarative way to apply CSS custom properties (variables) directly from Handlebars templates. It bridges the gap between JavaScript data and CSS styling in Ember applications, enabling dynamic theming and responsive design patterns.

Key Features

• Safe CSS Variable Injection — Applies CSS custom properties to DOM elements without manual DOM manipulation.
• Declarative Template Syntax — Uses a simple {{css-vars}} modifier in Handlebars for readable, maintainable code.
• Ember.js Integration — Built as a native Ember modifier, compatible with Ember 3.13+ and modern Ember CLI workflows.
• Scoped Styling — Variables are applied directly to specific elements, avoiding global CSS pollution.

Philosophy

The project emphasizes a declarative, framework-native approach to styling, keeping CSS variable logic within templates where it’s most relevant and reducing reliance on JavaScript-driven style overrides.
