How to verify bootstrap form
Article Introduction：Bootstrap provides form verification capabilities that can be added to projects by importing CSS and JavaScript. Create a form element and force the fields or pattern attributes to be filled in with the required attribute to verify a specific format. You can also customize the verification message.

FAQ: Disable verification removes the required and pattern attributes; the checkValidity() method can be manually triggered; the validity attribute can obtain the verification result.
