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.
Syntax
The <u>
tag is written as <u>
</u>
with the non-textual annotation inserted between the start and end tags.
Like this:
Examples
Misspellings
