In WordPress MVC (WPMVC), assets and resources — including CSS, JavaScript, images, fonts, SVGs, and other static files — are organized in a dedicated `/assets` folder at the root of your plugin or theme. This structure keeps all frontend and admin-facing files neatly separated from PHP logic, making them easy to manage, version, and deploy..
Any front-end file, non-PHP, is considered an asset in the framework; JavaScript, CSS, SASS, SCSS, LESS, fonts, images and views (templates) are examples of asset files.
CSS and SASS style assets are supported out-of-the-box.
JavaScript assets are supported out-of-the-box.
