::spelling-error CSS pseudo-elementThe ::spelling-error CSS pseudo-element represents a text segment which the user agent has flagged as incorrectly spelled.
The ::spelling-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.
Only a small subset of CSS properties can be used in a rule with ::spelling-error in its selector:
colorbackground-colorcursorcaret-coloroutline and its longhandstext-decoration and its associated propertiestext-emphasis-colortext-shadow::spelling-error {
/* ... */
}In this example, eventual supporting browsers should highlight any flagged spelling errors with the styles shown.
<p contenteditable spellcheck="true">
My friends are coegdfgfddffbgning to the party tonight.
</p>::spelling-error {
text-decoration: wavy red underline;
}
