Allow checkbox text to be right of the button

In cases with many individual checkboxes (such as product selection or email preference centers), I want my checkbox to be on the left and text to be on the right. Default now is for the text to be after your label. I've heard you can use CSS to fix this, but the examples I've found on Community aren't working and my email preference center looks messy - either I have checkboxes near the end of my labels of vastly different sizes (because they have different character counts), or I standardize the field width and in some cases my checkbox is far away from it's corresponding text. If I could switch field label and checkbox, this would be much cleaner.
