Adjust configurable list width with css

I would like each row in the configurable list to dynamically expand to fit the form width. Can you please help me with adjusting the iframe/container/table configurable list (not sure which).

You can try this method on how to make it more responsive: How-to-Make-the-Configurable-List-Widget-Mobile-Responsive

I have cloned your form and implemented this method. Please see below link for you to try:
