How to Set a Maximum Character Limit on an HTML input Element?

Find out how you can set maximum character requirement on an HTML input

You can use the maxlength attribute (which is very well-supported across different browsers) on the HTML <input> element to limit the maximum number of characters that a user can enter. For example:

<input type="text" maxlength="10" />

This would limit the user input in the <input> element to a maximum of 10 characters (as UTF-16 code units).

Please note that if no maxlength is set on the <input> element, or a non-positive integer value is set, then no maximum character limit is imposed.
