# Requires Input behavior
#
# When called on a form with input fields with the `required` attribute, the
# form's submit button will be disabled until all required fields have values.

#
# ### Example Markup
#
# <form class="js-requires-input">
# <input type="text" required="required">
# <input type="submit" value="Submit">
# </form>
