HTML5 workshop, forms
6 likes4,150 views
The document discusses new HTML5 form types, attributes, and elements. It provides examples of new input types like color, date, and range. It also covers new form attributes, validation methods and styles. Validation is improved but still has limitations. Styling is introduced for states like required, valid, invalid and focused using CSS pseudo-classes. Custom validation messages can be set but override the default checkValidity method.
