I've been looking at redesigning some asset level pages (articles, etc) lately. Currently on these articles we have a font size option (small, medium and large). Unfortunately it isn't something I can get any metrics on (nor done any testing) and am wondering if anyone has any experience with the usage of these.
It seemed like a lot of sites were including these kinds of controls a few years ago, but I'm noticing a lot of new sites (or redesigned sites) left this functionality off. Have people found that this kind of functionality is little used?
