a11y/iframe-title

Dlaczego

Screen readers announce an iframe by its title. Without one, people hear "frame" and must enter it to find out whether it is a video, a map or an advert, often on every page.

Poprawka

Add title with a short description of the content: title="Product video: setting up sync", title="Card payment form". Embeds from component libraries usually accept a title prop; pass it. Hide purely technical frames with hidden or aria-hidden="true" and tabindex="-1".
