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