Explainer https://github.com/WICG/responsive-image-client-hints/blob/master/Viewport-Height-Explainer.md Specification https://wicg.github.io/responsive-image-client-hints/#sec-ch-viewport-height Summary Currently, Responsive Image Client Hints provide a way for origins to obtain the viewport’s width. However, no such attribute exists for viewport height. We’ve observed that to optimize the loading of content that appears in viewport, it is essential for the origins to adapt HTML response based on viewport height.
