> * ... and the `viewport` definition makes it clear that this is the area and through which users can interact with the content: "User agents for continuous media generally offer users a viewport (a window or other viewing area on the screen) through which users consult a document." Terms that were unambiguous at the time a spec was written can become less clear when the spec is applied in a new context such as mobile browsing. "Viewport" is an example of such a term. In mobile browsers, the ability to pinch-zoom the page without reflowing it (which implies pinch-zooming does not change the initial containing block (ICB) from which page elements derive their sizes) has meant that the "viewport" used to derive quantities such as the ICB or scroll positions reported via `window.scrollX/Y` is not necessarily the same as what's currently visible on screen. The [Web Viewports Explainer](https://github.com/bokand/bokand.github.io/blob/master/web_viewports_explainer.md) document provides good background information on this subject. -- GitHub Notification of comment by theres-waldo Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/4329#issuecomment-731628083 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
