1. CSS overflow property

    Originally a single property for controlling overflowing content in both horizontal & vertical directions, the `overflow` property is now a shorthand for `overflow-x` & `overflow-y`. The latest version of the specification also introduces the `clip` value that blocks programmatic scrolling.

  2. 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

  3. CSS overflow: overlay

    The `overlay` value of the `overflow` CSS property is a non-standard value to make scrollbars appear on top of content rather than take up space. This value is deprecated and related functionality being standardized as [the `scrollbar-gutter` property](mdn-css_properties_scrollbar-gutter).

  4. CSS overscroll-behavior

    CSS property to control the behavior when the scroll position of a scroll container reaches the edge of the scrollport.

  5. Dynamic Adaptive Streaming over HTTP (MPEG-DASH)

    HTTP-based media streaming communications protocol, an alternative to HTTP Live Streaming (HLS).

  6. CSS3 Text-overflow

    Append ellipsis when text overflows its containing element

  7. CSS3 Overflow-wrap

    Allows lines to be broken within words if an otherwise unbreakable string is too long to fit. Currently mostly supported using the `word-wrap` property.
