::grammar-error

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

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:

css

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

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

html

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

css

::grammar-error {
  text-decoration: underline red;
  color: red;
}
