Building an accessible accordion

Aurooba and Brian dig into the semantics of not only what makes an accordion accessible, but also why a11y should be a first class consideration when you build anything on the web. They also explore how different ARIA tags work and what they indicate, taking a previously inaccessible accordion and transforming it into something navigable visually, with a keyboard, and with other assistive devices. Along the way, they also think out loud about the definition of an accordion and what that really means.
