🛠  Usage

WITHOUT "tallest" equalization

---
import { Tabs } from 'astro-tabs';
// ...
---

<Tabs class="pass-your-own-class" class:list={['pass-your-class-list']}>
	<Fragment slot="tab-1">Tab 1</Fragment>
	<Fragment slot="tab-2">Tab 2</Fragment>
	<Fragment slot="tab-3">Tab 3</Fragment>

	<Fragment slot="panel-1">
		<h2>Panel 1</h2>
		<p>Hello world</p>
	</Fragment>

	<Fragment slot="panel-2">
		<h2>Panel 2</h2>

		<img
			height="400"
			src="https://res.cloudinary.com/dzfylx93l/image/upload/v1664340439/astro-takeoff-1_ecdfxf.gif"
		/>
	</Fragment>

	<Fragment slot="panel-3">
		<h2>Panel 3</h2>
	</Fragment>
</Tabs>

WITH "tallest" panel equalization, use panel-<n>-tallest

<Tabs>
	<Fragment slot="tab-1">Tab 1</Fragment>
	<Fragment slot="tab-2">Tab 2</Fragment>
	<Fragment slot="tab-3">Tab 3</Fragment>

	<Fragment slot="panel-1">
		<h2>Panel 1</h2>
		<p>Hello world</p>
	</Fragment>

	<!-- v———————————————————————————————————— This is the tallest panel -->
	<Fragment slot="panel-2-tallest">
		<h2>Panel 2</h2>
		<img
			height="400"
			src="https://res.cloudinary.com/dzfylx93l/image/upload/v1664340439/astro-takeoff-1_ecdfxf.gif"
		/>
	</Fragment>

	<Fragment slot="panel-3">
		<h2>Panel 3</h2>
		<p>Heya</p>
	</Fragment>
</Tabs>
