Validating a will
Client-side validation alone does not ensure security; therefore data needs to be validated on the server-side as well.
Forms frequently include required input that needs to be clearly identified using labels.
If your web browser supports HTML5, it will not allow you to submit the form without entering text into the input field.
Instead, it will display a message that is generated by the web browser itself.

For example, postal codes aren't confined to just numbers in some countries, so using an can easily become a problem for many of your website users.Where possible, require user confirmation for irreversible actions, such as permanent deletion of data.
