Problem Statement
What does the novalidate attribute on a form do?
Explanation
The novalidate attribute disables HTML5 form validation. When you add novalidate to a form tag, the browser skips all client-side validation checks when the form is submitted. Fields with required, pattern, min, max, and other validation attributes are not checked. The form submits immediately without showing validation error messages. This is useful when you want to handle all validation with JavaScript or when testing forms during development. You can also use the formnovalidate attribute on submit buttons to bypass validation for specific submit actions. For example, a Save Draft button might use formnovalidate to allow saving incomplete forms, while the main Submit button validates normally. However, disabling client-side validation means you must rely entirely on server-side validation for data quality and security.
