::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.

Allowable properties

Only a small subset of CSS properties can be used in a rule with ::grammar-error in its selector:

Syntax

css
::grammar-error {
  /* ... */
}

Examples

In this example, eventual supporting browsers should highlight any flagged grammatical errors with the styles shown.

  My friends is coming to the party tonight.
</p>

CSS
