First, you need to include the jQuery library in your web page.

Next, add a form to your web page that includes input fields with appropriate validation attributes.

Use the jQuery validation plugin to validate the form inputs. This is done by calling the .validate() method on the form element.

Attach error messages to each invalid input field using the .rules() method.

Submit the form and intentionally enter invalid data to trigger the error messages.

Check the console for any error messages that may have been generated by the validation plugin.

View the error page by intentionally entering invalid data that cannot be validated by the plugin.

Customize the error page to suit your needs.
