<em>

The HTML <em> element highlights text for emphasis, usually rendered in italics, to suggest importance or a shift in meaning or tone.

<em> Tag

The <em> tag is used to emphasize text, with most browsers displaying it in italics. Unlike the <i> tag, which also italicizes text, <em> conveys meaning by indicating emphasis rather than just visual styling.
