📃 December 2011 release notes

New in Chrome

The following features are now available in Chrome:

  • <bdi>: The <bdi> element isolates text that may have a different text direction from its surrounding text. This prevents the browser's bidirectional text algorithm from affecting or being affected by the direction of the surrounding text.
  • cubic-bezier() easing: The cubic-bezier() CSS easing function interpolates along a smooth curve, creating animations and transitions with continuous changes in speed. The ease, ease-in, ease-out, and ease-in-out keyword values are presets for common Bézier curves.
  • hashchange: The hashchange event fires when the URL fragment identifier (the part of the URL starting with #) of the current page has changed.

New in Firefox

The following features are now available in Firefox:

  • background-size: The background-size CSS property scales or stretches a background based on the size of the element (with the contain and cover keywords), a length, or percentage.
  • Custom ellipses: The text-overflow CSS property with a string value sets the string representing clipped text.
  • font-stretch: The font-stretch CSS property selects a font face from a font family based on width, either by a keyword such as condensed or a percentage.

  • Custom ellipses: The text-overflow CSS property with a string value sets the string representing clipped text.
