## Problem It isn't clear if a "selected" button should only be styled like it's selected, or use `aria-pressed`. ## Solution Document the difference between a selected style and `aria-pressed` and consider when they could be used in conjunction, or extend the `.selected` class to the `aria-pressed` attribute. Update the stories to account for the above. - [`aria-pressed`](https://www.w3.org/TR/wai-aria-1.1/#aria-pressed) is ideal for a toggle button. The resulting button should leverage the selected styles when `aria-pressed="true"`. - A `.selected` style can be applied to a button that represents the current UI, even though the button can still be enabled.
