Video Player Forcing Landscape Fullscreen for Ordinary Content

1.3.4 — Orientation

Scenario

Setting

A car-rental site's checkout flow

What’s wrong

Video player forcing landscape fullscreen with no portrait playback for non-essential content.

Example

@media (orientation: portrait) { .app { display: none; } }

Why it matters

People whose devices are mounted or who cannot rotate a display freely.

How to test

Rotate to portrait during video playback: if the player forces landscape fullscreen with no portrait playback option for non-essential video, it fails.

How to fix

The page/app must remain fully usable in both portrait and landscape, with the layout intact after rotation. /* Layout adapts with responsive CSS in both orientations instead of blocking one */ Content must work in both portrait and landscape unless a specific orientation is essential.

Outcome

On a car-rental site's checkout flow, this barrier is gone for people whose devices are mounted or who cannot rotate a display freely — they reach the same outcome without extra effort.

Who is affected

People whose devices are mounted or who cannot rotate a display freely.
