HTML <u> Tag

The HTML <u> tag represents text with an unarticulated, though explicitly rendered, non-textual annotation. This could include words or spans of text that need to be presented differently such as misspelt words or Chinese names.

Prior to HTML5, the <u> tag was used purely for presentational purposes (to underline text). However, this has changed and from HTML5, the <u> element has a more specific semantic purpose (as outlined above). If your intention is simply to underline text (without conveying any other meaning), use the text-decoration property instead.

Most browsers/user agents underline text that is marked up with the <u> tag. For this reason, you should avoid using this element in cases where it may be confused for a hyperlink. Alternatively, you could use CSS to style the text so that it is differentiated from hyperlinks.


The <u> tag is written as <u></u> with the non-textual annotation inserted between the start and end tags.

Event Handlers

Event handler content attributes enable you to invoke a script from within your HTML. The script is invoked when a certain "event" occurs. Each event handler content attribute deals with a different event.

Most event handler content attributes can be used on all HTML elements, but some event handlers have specific rules around when they can be used and which elements they are applicable to.

For more detail, see HTML event handler content attributes.
