Em Tag
The <em> tag is used to emphasize text in an HTML document. This can be done by wrapping the text you would like to be emphasized in an <em> tag and an </em> tag respectively. Most browsers will render text wrapped in an <em> tag as italicized.
Note: The <em> tag should not be used to stylistically italicize text. The <em> tag is used to stress emphasis on text. Typically, CSS formatting is used to stylistically italicize text.
Example:
<body>
<p>
Text that requires emphasis should go <em>here</em>.
</p>
</body>
