HTML5 Reference

HTML <u> tag

Definition

The <u> tag is used for representing a span of text with an Unarticulated, non-textual annotation, such as proper names in Chinese text or misspelt words.

The <u> tag should not be used for underlining from HTML5 onwards as was the case in earlier versions of HTML, even though it will generally be rendered underlined in browsers

Use css attributes such as the CSS text-decoration property for underlining text.

Example


<p>People with cockney accents don't always pronounce their words <u>proper</u>.</p>

People with cockney accents don't always pronounce their words proper.
