HTML <u> style Attribute

The style attribute on a <u> tag assigns a unique style to the underlined text. A style contains one or more CSS property/value pairs that define the appearance of the u element.

Example

#

A style attribute on a <u> tag.

<p>
  <u style="color:navy;background-color:aliceblue;">This text is underlined</u>.
</p>

Using style

The style attribute specifies the style, i.e. look and feel, of the <u> element.

A style contains any number of CSS property/value pairs, separated by semicolons (;).

The style attribute overrides any other style that was defined in a <style> tag or an external CSS file.

This inline styling affects the current <u> element only.
