Installation

import { LionTabs } from '@lion/tabs';
// or
import '@lion/tabs/define';

Rationale

No separate active/focus state when using keyboard

We will immediately switch content as all our content comes from light dom (e.g. no latency)

See Note at https://www.w3.org/TR/wai-aria-practices/#keyboard-interaction-19

It is recommended that tabs activate automatically when they receive focus as long as their associated tab panels are displayed without noticeable latency. This typically requires tab panel content to be preloaded.

Panels are not focusable

Focusable elements should have a means to interact with them. Tab panels themselves do not offer any interactivity. If there is a button or a form inside the tab panel then these elements get focused directly.
