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 considered to be a phrase tag, which points out that a section of the text has a structural meaning.
The <em> tag comes in pairs. The content is written between the opening (<em>) and closing (</em>) tags.
Example of the HTML <em> tag:¶
<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>
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.
