    <u>

    Summary

    The HTML Underline Element (<u>) renders text with an underline, a line under the baseline of its content.

    In HTML5, this element represents a span of text with an unarticulated, though explicitly rendered, non-textual annotation, such as labeling the text as being a proper name in Chinese text (a Chinese proper name mark), or labeling the text as being misspelled.

    Usage Note: As with all purely styling elements, <u> has been deprecated in HTML 4 and XHTML 1, but it has been re-introduced in HTML5 with other semantics. If you want to underline text in a non-semantic manner, you should use a <span> element, or another semantically appropriate element, and style it with the CSS text-decoration property, with the underline value.

    Attributes

    This element only includes the global attributes.

    Tips and Notes

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

    Note: The HTML 5 specification reminds developers that other elements are almost always more appropriate than <u>.

    DOM interface

    This element implements the HTMLElement interface.

    Implementation note: up to Gecko 1.9.2 inclusive, Firefox implements the HTMLSpanElement interface for this element.

    Example

    <u>Today's Special</u>: Salmon<br />
<span style="text-decoration:underline;">Today's Special</span>: Salmon

    Today's Special: Salmon

    Today's Special: Salmon

    <p><u>All</u> of that is explained in <u>Dive into Python</u>.

    All of that is explained in Dive into Python.

    should instead be

    <p><em>All</em> of that is explained in <cite>Dive into Python</cite>.

    All of that is explained in Dive into Python.

    CSS can be used to style those elements exactly the same, however.

    See Also

    • The <span>, <i>, <em>, and <cite> elements are, depending on the case, to be used instead.
    • The CSS text-decoration property is to be used to achieve the former visual aspect of the <u> element.
