selector list argument of :nth-child and :nth-last-child CSS pseudo-classes
The newest versions of :nth-child() and :nth-last-child() accept an optional of S clause which filters the children to only those which match the selector list S. For example, :nth-child(1 of .foo) selects the first child among the children that have the foo class (ignoring any non-foo children which precede that child). Similar to :nth-of-type, but for arbitrary selectors instead of only type selectors.
Non-standard method of scaling content.
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 ::marker pseudo-element
The ::marker pseudo-element allows list item markers to be styled or have their content value customized.
Method of easily creating custom dialog boxes to display to the user with modal or non-modal options. Also includes a ::backdrop pseudo-element for behind the element.
