They said "You may as well just do 'serif' or 'sans-serif' and be done with it." > Now I understand that you also say that default fonts are not necessarily well designed. While fonts are a matter of taste, objectively speaking fonts that comes preinstalled on systems often have very few weights and support only a very limited range of glyphs. They also lack features such as small caps, old-style numbers, etc. Usually, though, the main, default sans-serif and/or UI font on the system are much better than some random font that just happens to be included in the system. So you will usually be better off using `sans-serif` than any of these font stacks. > I guess that happens when people assume that the web font will be loaded and don't default to (sans-)serif in their font-familly CSS property. But this is just yet another reason why using font stacks is bad...? If instead you just use `serif` or `sans-serif` it will follow the user's font preference.
