Ensuring everyone can interact with content

User interface components and navigation must be operable.

The beauty of the web is how interactive and immersive it is. I am always amazed, and grateful, at how the web started off as just static content to now driving complex functionality with full-blow applications in the browser. But everyone needs to be able to navigate and interact with content.

To be clear, accessibility is not a checklist or a tool, and doing everything exacly as documented here will not always guarantee an accessible, or compliant site. It's important to note that how you deliver accessibility is unique and completely dependant on your particular site content, and users.
