The following is an example form taken from Inayaili de León's tutorial on HTML5 forms. The only thing different from the original is that I have added Weston Ruter's webforms2 to implement HTML5 form validation in browsers that don't natively support it. This change required only one script tag. Back to the User Agent Man HTML5 Forms article.
