Styling Express Forms
With the way Express Forms render it's pretty complicated to make a custom template for them. I'l like to suggest that there be a class option added to forms, so if you wanted to you could add your own class names to questions.
Then the div that wraps each question that has class="form-group" could be "form-group my-class-name etc etc". It would make a world of difference in being able to style forms.
