HTML <em> Tag

The <em> tag specifies a text that has stress emphasis. Browsers display the text within this tag in italic.

The <em> tag is an element of logical markup in contrast to the <i> tag, which has the same visual effect (italic), but at the same time, doesn’t carry a semantic load.

The <em> tag is not deprecated, but it is possible to achieve richer effects with CSS font-style property .

The <em> tag is considered to be a phrase tag, which points out that a section of the text has a structural meaning.

Syntax

The <em> tag comes in pairs. The content is written between the opening (<em>) and closing (</em>) tags.

Example of the HTML <em> tag:

<!DOCTYPE html>
<html>
  <head>
    <title>Title of the document</title>
  </head>
  <body>
    <p>It is a normal paragraph</p>
    <p>The important part of the text is highlighted by the <em> in italic</em>.</p>
  </body>
</html>

Result

The difference between the <em> and the <i> tags

The <em> and <i> tags are usually confused, because they create similar results because both of them italicize the text. However, the results are the same only visually. The <em> element specifies the text that has stress emphasis, while the <i> tag defines a part of the text in a different voice. It is usually used to define technical terms, phrases from foreign languages, etc.

Attributes

The <em> tag supports the Global Attributes and the Event Attributes.
