HTML <mark> Tag
<mark> tag represents text as marked or highlighted for reference purposes, due to its relevance in another context.
There are two main contexts for the
<mark> tag. Here's how the HTML 5 specification explains it:
When used in a quotation or other block of text referred to from the prose, it indicates a highlight that was not originally present but which has been added to bring the reader's attention to a part of the text that might not have been considered important by the original author when the block was originally written, but which is now under previously unexpected scrutiny. When used in the main prose of a document, it indicates a part of the document that has been highlighted due to its likely relevance to the user's current activity.
<mark> tag is written as
</mark> with the text being marked up inserted between the start and end tags.
