Who would know why you took off that term? You might have been ill. You might have had financial issues. Maybe your family needed you. Maybe you felt online-only classes don't warrant the university fee. Or maybe an essential in-person lab wasn't available to you.
Would you still live on campus so you could engage in any essential ECs you are already involved in? If not, how do you afford your monthly rent payments? Would your presence at home endanger any older folks living there if you don't plan to "lock down?" Will the college grant you a leave of absence so you don't have to reapply in order to return next fall?
There are a lot of considerations, but, no, it won't "look bad" to take off a term of college.
