Generally don’t underline text on the web that is not a link. Underlines are strongly perceived to be a clickable link which will confuse and frustrate users. Use '''strong''' or '''em''' or header tags to denote importance and avoid the '''u''' tag. The U tag is not intended to convey semantic meaning. According to W3C https://www.w3schools.com/tags/tag_u.asp underline text should only be used for things like misspelled words or proper names in Chinese.
