CSS Backdrop Filter

CSS background-repeat round and space
Allows CSS background images to be repeated without clipping.
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
CSS widows & orphans
CSS properties to control when lines break across pages or columns by defining the amount of lines that must be left before or after the break.
CSS Device Adaptation

selector list argument of :not()
Selectors Level 4 allows the :not() pseudo-class to accept a list of selectors, which the element must not match any of. Selectors Level 3 only allowed :not() to accept a single simple selector. Thus, :not(a):not(.b):not([c]) can instead be written as :not(a, .b, [c])
CSS font-rendering controls
@font-face descriptor (currently defined as font-display) that allows control over how a downloadable font renders before it is fully loaded.
#rrggbbaa hex color notation
The CSS Color Module Level 4 defines new 4 & 8 character hex notation for color to include the opacity level.
CSS Motion Path
