Shadcn Content Block One

An expandable long-form content card with a read-more button, height animation, and masked overflow.

This content section is a client component: it stores isFull in React state, toggles between Plus and Minus, and animates height with motion.div. The demo prose is placeholder commencement-copy material, so the useful source detail is the interaction model rather than the sample story.

Use this when a product page needs a compact explanation that can expand for readers who want more detail. The shadcn Button, Tailwind mask utility, rounded card, ring, and shadow give the section enough structure for onboarding copy, founder notes, or a product philosophy excerpt.

The implementation is regular React and Tailwind CSS, so it can sit inside a Next.js route alongside other shadcn UI blocks. Ground the final copy in product evidence, especially where the source demo text is placeholder or borrowed.

What to customize

Replace the placeholder speech text with real product explanation.
Keep the collapsed height aligned with the strongest opening paragraphs.
Check the read-more button position after changing copy length.

Implementation notes

Is this a content section or a feature section?

It is a content section: the source prioritizes explanation, media, and supporting copy over a dense feature grid.

Can I use it with shadcn?

Yes. Several variants use shadcn-compatible primitives such as Button and AspectRatio, while the rest are local markup styled with Tailwind CSS.
