HTML <u> Tag


Mark up a misspelled word with the <u> tag:

<p>This is some <u > mispeled</u> text.</p >

Definition and Usage

The <u> tag represents some text that is unarticulated and styled differently from normal text, such as misspelled words or proper names in Chinese text. The content inside is typically displayed with an underline. You can change this with CSS (see example below). 

Tip: Avoid using the <u> element where it could be confused for a hyperlink!
