::grammar-error
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
The ::grammar-error CSS pseudo-element represents a text segment which the user agent has flagged as grammatically incorrect.
The ::grammar-error pseudo-element follows a special inheritance model common to all highlight pseudo-elements. For more details on how this inheritance works, see the Highlight pseudo-elements inheritance section.
