Second Project-Survey/larger radio buttons

I have my radio buttons put into my project but they are not congruent with the size of my font is there a way to just adjust the size of the buttons? and if so could you point me in the right direction? My first thought was to put an id="" for each radio button and make them larger in css or actually use the class function… but things don’t seem to be coming out right… is one of these two things the answer?
Thank you in advance for your consideration,
Christine
