U Usage:
underlined text
<u>This text is underlined</u> but it’s not a link.
It’s better to use the text-decoration style:
<span style="text-decoration: underline;">This text is underlined</span> but it’s not a link
U Special Notes:
- The U tag has been deprecated in favor of CSS. You should use the text-decoration style property instead of this tag.
- Keep in mind, when you use this tag, that links are typically underlined, and having non-linked text underlined can frustrate your readers.
