pub(crate) fn normalize_css_property_name(prop: &str) -> StringExpand description
Converts a camelCase CSS property name to its hyphenated form.
Custom properties (--*) are returned as-is. Vendor-prefixed properties
(e.g. MsTransition, WebkitTapHighlightColor) are converted to their
standard hyphenated forms (-ms-transition, -webkit-tap-highlight-color).
