04 Form submit

Notable points

• Handle form submit event instead of button click event
• Give type="button" to buttons that should not submit the form, if any
• Prefer :user-invalid to :invalid
• It might be a good idea to replace type="email" with something else
  • Because type="email" doesn't support Japanese domain name and etc.
  • type=”email”は使わない方が良いんじゃないか（ちょっと良いUIおれおれAdvent Calendar 2024 – 22日目）
• Never think like client side validation is enough
• Actually there must be much much more things we have to consider
