Use this page to check support and appearance of HTML5 form controls for your browser. Play around with them and submit the form (using the submit or image control in the "buttons" section below) to see how the data is handled.
The form submits to itself using the GET method. So all the data is passed via the query string. A javascript on the page will evaluate the query string and display the submitted data conveniently.
Feel free to edit the document locally and play more around.
