Survey Form Checkbox Spacing

Tell us what’s happening:
I’m working on the survey form project and can’t seem to figure out how to space my checkboxes evenly. I have them in a fieldset, each with their own labels and inputs, obviously. In my CSS, which I am still very new to, I’m trying to get my checkboxes to be evenly spaced between each other (my main goal was to have two columns of 5 checkboxes, but that may be too complicated for me, right now). I have the flex box, and the flex direction which work, but the justify-content won’t do what I though it would, and I cannot figure out why. Any help would be appreciated. Thanks!
