Back to SnippetsCharacter counter with a real maxlength and review state
A compact textarea helper with an actual maxlength, visible counter, near-limit state, reset behavior, and no fake submission.
HTMLCSSJavaScript
Receipt: the visible count and browser-enforced limit always agree.
What this is
Show the limit before the form says no.
Use this for bios, captions, announcements, support notes, or any field with a meaningful content limit.
Use it
- Set maxlength on the textarea and read that same property when updating the counter.
- Test typing, paste, reset, empty submission, and the near-limit state.
Make it yours
- Change maxlength and the near-limit percentage without maintaining a second hard-coded limit.
- Replace the demo review state with your validated submission handler.
Reuse contract
Supported environments
- Current Chrome, Edge, Firefox, and Safari
- Static forms and CMS templates
Security notes
- Client maxlength improves usability but is not server-side validation.
- Apply server-owned length, type, authorization, and rate-limit checks before storage or delivery.
