CSS background-position edge offsets
Allows CSS background images to be positioned relative to the specified edge using the 3 to 4 value syntax. For example: `background-position: right 5px bottom 5px;` for positioning 5px from the bottom-right corner.
CSS Motion Path
Allows elements to be animated along SVG paths or shapes via the `offset-path` property. Originally defined as the `motion-path` property.
CSS overflow-anchor (Scroll Anchoring)
Changes in DOM elements above the visible region of a scrolling box can result in the page moving while the user is in the middle of consuming the content. By default, the value of `overflow-anchor` is `auto`, it can mitigate this jarring user experience by keeping track of the position of an anchor node and adjusting the scroll offset accordingly
