HTML - min Attribute

For input elements such as <input type="number">, <input type="date">, or <input type="time">, the min attribute in HTML is used to define the minimal value. It establishes a lower bound on the allowable input range. For date and time input, it makes sure that the selected date or time is not earlier than the given minimum, and it prevents values below the defined minimum for numeric input.

By limiting input to a predetermined lower boundary, this attribute is essential for designing user-friendly forms and ensuring data consistency.

Syntax

Following is the syntax of the HTML min attribute −

<input min="number|date">

Example

In the following example, we are using the min attribute with the input type=number.

<!DOCTYPE html>
<html lang="en">
<head>
   <title>HTML min attribute</title>
</head>
<body>
   <!--Example of the 'min' attribute-->
   <form> Enter your age (not less than 18): <input type="number" min="18">
      <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. when the user enters the values that is below 18 it will throw a exception.

Example

Considering the another scenario, where we are going to use the min attribute with th input type=date.

<!DOCTYPE html>
<html lang="en">
<head>
   <title>HTML min attribute</title>
</head>
<body>
   <!--Example of the 'min' attribute-->
   <form> Choose a date(not less than 2023-06-10): <input type="date" min="2023-06-10">
      <button>Submit</button>
   </form>
</body>
</html>

On running the above code, the output window will pop up displaying the input field of date type along with a submit button on the webpage.

Example

Let's look at the following example, where we are going to use both min and max attribute with the same input type.

<!DOCTYPE html>
<html lang="en">
<head>
   <title>HTML min attribute</title>
</head>
<body>
   <!--Example of the 'min' attribute-->
   <form> Enter a number (between 10 to 50): <input type="number" min="10" max="50">
      <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.
