HTML: tag

The text defined by the HTML tag should be styled differently or have non-text annotations. Traditionally, browsers will display the text found within the tag as underlined text. This tag is also commonly referred to as the element.

Tip: If you want to underline text, you should use CSS (for example, text-decoration attribute) instead of markers. Note that the underlined text should not be confused with hyperlinks.

Online Example
