What is HTML Mark Text Generator?

The HTML `<mark>` element highlights text that is relevant or noteworthy in a particular context. Browsers render it with a yellow background by default (overridable with CSS). The key semantic distinction is that `<mark>` indicates relevance in the current context — not general importance like `<strong>`.

The most common use case is highlighting search query matches in search result snippets. Another use is annotation systems that highlight passages a user has marked for review. The `<mark>` element was introduced in HTML5 specifically for this "highlighted for reference" semantic.

Frequently Asked Questions

What is the difference between <mark> and <strong>?

<mark> indicates relevance in the current context — typically a search match or annotation. <strong> indicates strong importance in the overall content. Use <mark> for "found what you searched for" and <strong> for "this is important to understand".

Can I change the highlight colour?

Yes. Use CSS: mark { background-color: #yourcolour; color: inherit; }. The default yellow is a browser default, not part of the HTML specification.
