<link rel="author" title="Gérard Talbot" href="http://www.gtalbot.org/BrowserBugsSection/css21testsuite/">
<style>
textarea
{
font-size: 300%;
}
textarea::grammar-error
{
color: maroon;
text-decoration: underline dotted red;
}
</style>
<p>PREREQUISITE: User agent needs to have an enabled and capable grammar error module. If it does not, then this test does not apply to such user agent.
<p>Test passes if each glyph of "thing" is maroon and if "thing" is underlined with a red dotted line.
<div><textarea cols="20" rows="2">Many thing can happen</textarea></div>
