The <em> Tag in HTML 5
The <em> tag indicates that the content should be emphasized for some reason. The em element is one of the phrase elements in HTML. The appearance of text enclosed within a em element is often rendered with an italic font, the same as for the HTML <i> tag, which does not imply increased importance.
<em> Tag Syntax
<body> ... ... phrasing content expected ...<em>... phrasing content ...</em>... ... </body>
Rules for coding HTML em elements
Make sure you understand the difference between a tag and element and are familiar with the definitions of namespace and other HTML terms.
- Code the em element for emphasized text where phrasing content is expected.
- Begin the em element with a starting <em> tag. The element name uses lower case letters and should be in the HTML namespace, which it will pick up automatically from the
xmlnsattribute on the <html> tag. - Include any HTML global attributes on the <em> tag as appropriate.
- Inside the em element, between the starting
<em>tag and the ending</em>tag, code the inner HTML phrasing content. - End the em element with a matching
</em>closing tag.

Differences between HTML 5 and earlier versions of HTML
The 2000-2010 Recommendations from the W3C HTML Working Group defined the HTML namespace for the em element type name along with the names of all HTML element types. In older (pre-2000) versions of HTML, element type names were not associated with a namespace.
