The novalidate attribute on a <form> tag turns off validation for all input elements during form submission.
When enabled, no input elements inside the form will be validated.
A novalidate attribute on a <form> element.
This setting overrides the required attributes on the input elements.
<form action="/tutorial/action.html" novalidate>
<input type="text" name="firstname" placeholder="First name" required>
<input type="text" name="lastname" placeholder="Last name" required>
<button type="submit">Submit</button>
</form>
The novalidate attribute specifies that no form validation takes place.
With this attribute enabled, none of the input elements will be validated, even when specified.
Effectively, form novalidate overrides all the input element's validation settings.
