HTML - maxlength Attribute

The HTML maxlength attribute is used to define the maximum number of characters the user can enter into an input and textarea field. The value of the maxlength attribute must be an integer 0 or higher(more than 0).

If no maxlength value is specified, or any invalid value is specified, the input and textarea have no maximum length. The maxlength value must be greater than or equal to the value of the minlength attribute.

Syntax

Following is the syntax of the HTML maxlength attribute −

<tag maxlength = "value">

Example

In the following example, we are going to use maxlength attribute with the input type=text.

<!DOCTYPE html>
<html lang="en">
<head>
   <title>HTML 'maxlength' attribute</title>
</head>
<body>
   <!-- example of the HTML 'maxlength'-->
   <form>
      <input type="text" maxlength="10">
      <button>Submit</button>
   </form>
</body>
</html>

When we run the above code, it will generate an output consisting of the input field along with a click button on the webpage.

Example

Considering the another scenario, where we are going to use the maxlength attribute with the textarea element.

<!DOCTYPE html>
<html lang="en">
<head>
   <title>HTML 'maxlength' attribute</title>
</head>
<body>
   <!-- example of the HTML 'maxlength'-->
   <form> Write your feedback: <br>
      <textarea name="" id="" cols="30" rows="5" placeholder="Your feedback...." maxlength="30"></textarea>
      <br>
      <button>Submit</button>
   </form>
</body>
</html>

On running the above code, the output window will pop up displaying the textarea field along with a click button on the webpage.
