No checking: In #CSS, what are the identifiers to indicate case (in)sensitivity in selectors?

The answer is:
i
ands
. Both identifiers are described in w3.org/TR/selectors-4/#attribute-case (draft). Support fori
is good (caniuse.com/css-case-insensitive), fors
it’s poor (caniuse.com/mdn-css_selectors_attribute_case_sensitive_modifier). Practical impact? Not that large, b/c case-sensitivity depends on the host language.
