HTML Mark Text Generator
Generate HTML that wraps chosen phrases with mark tags while escaping the rest safely. Copy snippets for blogs and tutorials.
Highlight critical phrases inline by wrapping literal matches inside semantic <mark> elements. The markup generator escapes everything except intentional tags so you preview safe snippets destined for templating frameworks or Markdown embeds.
Popular workflows
- Docs-as-code previews: Ship tiny HTML fragments into static site preprocessors needing explicit highlight spans.
- CMS partials: Authors paste sanitized sentences and choose exact keyword emphasis without risking raw injections.
- Accessibility tutorials: Demonstrate WCAG-aligned highlights instead of shouting with bold alone.
- Email snippet labs: Many clients respect
markinside inline HTML snippets when CSS resets keep yellow backgrounds.
How matching behaves
Regular-expression special characters entered in your phrase undergo escaping automatically. Optionally enforce Unicode-aware word boundaries around matches to avoid chopping substrings (“port” versus “transport”). Case-insensitive scans apply full-string flags respecting supplementary plane letters.
Frequently Asked Questions
Can I nest extra tags inside the textarea?
Yes, but escaping treats input as literal text—the tool does not traverse the DOM, it operates on strings. Highlights appear around raw character sequences even mid-tag.
Does the generator add CSS?
No—only markup. Attach your own stylesheet adjusting mark background and contrast ratios.
Will multiple occurrences be wrapped?
Every non-overlapping match receives its own highlight span using global matching.
Why keep whole-word matching on by default?
Whole-word guards reduce accidental partial replacements especially when keyword lists contain short stems.
