Multiple Choice Element - Increase Column Width

How can I increase the width of the columns in a multiple choice element?  I have used this element on one of my forms, and the columns are too close together for the options to be clear.

The multiple choice element in question on my form has the title "Sushi", about half-way down the form.

Thank you.

I checked your form and it looks like you have extended the field to the width of the form:

Are the columns still not wide enough?  Let us know and we can help with widening them further.  As far as I can tell though, you have already made the required adjustments.

Yes - shortly after posting my question I figured out the correct CSS to increase the column widths.
