HTML <mark> tag

The <mark> tag marks a part of the text which has relevance. It can be used to highlight text for showing emphasis, highlight search terms in search results to provide context; or distinguish new content added by user by showing it differently.

In the Chrome and Firefox the tag content is marked in yellow, but it can be changed with CSS background-color property .

The <mark> tag doesn’t have semantic content. In order to show the importance of the marked text, use the <strong> or <em> tags.


The tag content is written between the opening (<mark>) and closing (</mark>) tags.
