CAST Figuration

Figuration logo

CAST Figuration®️ is a package of CSS and JavaScript that can be used as a starting point for building an accessible, cross-device, interactive website. It contains styles for text and buttons; interactive elements such as navigation, dropdown menus, and modal dialogs; column and grid layouts that adapt to the screen and device in use; color schemes that pass WCAG contrast checks; and advanced components such as an HTML5 audio and video player with interactive captions. All components are built to be usable via mouse, keyboard, or touch interaction as well as accessible to screen readers and other assistive technologies. Originally created as part of the National AEM Center's work, continued updating and improvements are supported by all of CAST's website projects.

Figuration was originally based on Bootstrap v3, with the added goal to enhance and embed accessibility functionality into the widgets so it is automatically applied as needed. This approach accelerates functional updates without having to individually revise each project or module. In addition, this method means that development teams can create accessible sites without as much effort and specialized knowledge.

The Figuration widgets are all initialized and configured in a consistent way, using either HTML data attributes or JavaScript calls. They aim to save the developer time by taking care of a lot of the behind-the-scenes details. For instance, ARIA attributes are automatically added, browser differences are smoothed out, and special cases for touch devices are handled. While reasonable defaults are provided, all aspects of the design and functionality are customizable.

Figuration’s ongoing development has introduced many of the recent features, such as flexbox layout, and utility classes, that can be found in Bootstrap v4 and v5. In some cases we have made only slight changes to Bootstrap components for accessibility and consistency with our configuration scheme, while other Figuration components are built from scratch. Figuration leverages Sass to provide variables that can be used to customize visuals and layout, as well as provide the ability to remove portions of generated CSS for increased performance.
