webui: Fix input[type=number] validation; Add input validation styles

* Fix the validation for some "input[type=number]" element;
  By default, the number type input only accept *integer*. By setting
  the 'step="any"' attribute, the float numbers are also valid.
* Add form input validation styles for ":valid" and ":invalid" pseudo
  classes.
