HTML <u> tag

The HTML <u> element represents a span of inline text which should be rendered in a way that indicates that it has a non-textual annotation (such as misspelled words). This is rendered by default as a simple solid underline, but may be altered using CSS.

Run code

This element used to be called the "Underline" element in older versions of HTML, and is still sometimes misused in this way. To underline text, you should instead apply a style that includes the CSS text-decoration property.

Browser compatibility

The <u> element is fully supported by all browsers:

<u> yes yes yes yes yes
