Aspect ratio

Lock media to an inline-to-block ratio.

AspectRatio locks a frame to an inline-to-block ratio and sizes its direct child to fill the frame. Use it for media such as an iframe, img, or video. Images and videos use objectFit="cover" by default. Pass another objectFit value to change how they fit the frame. Read Layout to choose a layout component.
