HTML 5 <u> Tag

The HTML <u> tag is used for specifying text with a non-textual annotation. This could include words or spans of text that need to be presented differently such as misspelt words or Chinese names.

The <u> tag usually results in the text being underlined (unless you style it otherwise). For this reason, you should avoid using this element in cases where it may be confused for a hyperlink.

Note that the <u> tag was actually deprecated in HTML 4.01 and initially obsolete in the HTML5 specification. However, it has since returned to the HTML5 specification as a valid HTML element (with a different purpose).



HTML tags can contain one or more attributes. Attributes are added to a tag to provide the browser with more information about how the tag should appear or behave. Attributes consist of a name and a value separated by an equals (=) sign, with the value surrounded by double quotes. Here's an example, style="color:black;".

There are 3 kinds of attributes that you can add to your HTML tags: Element-specific, global, and event handler content attributes.

The attributes that you can add to this tag are listed below.

Element-Specific Attributes

The following table shows the attributes that are specific to this tag/element.


Global Attributes

The following attributes are standard across all HTML 5 tags (although the tabindex attribute does not apply to dialog elements).

For a full explanation of these attributes, see HTML 5 global attributes.

Event Handler Content Attributes

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.

For a full list of event handlers, see HTML 5 event handler content attributes.
