u!() { /* proc-macro */ }Expand description
<u> element.
The <u> HTML element represents a span of inline text which should be rendered in a way that indicates that it has a non-textual annotation. This is rendered by default as a simple solid underline, but may be altered using CSS.
Warning: This element used to be called the “Underline” element in older versions of HTML, and is still sometimes misused in this way. To underline text, you should instead apply a style that includes the CSS text-decoration property set to
underline.
See the Usage notes section for further details on when it’s appropriate to use <u> and when it isn’t.
