Please don't suggest to use px values for font-size

Use rem for Global Sizing; Use em for Local Sizing -> YES!

But… html { font-size: 16px; } -> pleaaaase noooo! :-/

@nhoizey thanks for the feedback. Your post is interesting. Are you advocating more for just html { font-size: 1em; } to let the default value be interited per browser?

@AllThingsSmitty thanks for reading it! ;-)

html { font-size: 1em; } is useless, as it is the default value. So I would advocate for nothing at all.

To be honest, I now use something a little more complex on the body to add some fluid responsiveness to my font-size, but I don't touch the html font-size at all and the value on body is meant to be equal to 1em or more, depending on viewport sizes.

@nhoizey That's a very interesting way of defining font size. Congrats on that. But can you please elaborate how you got to this specific value .8em+.3vw+.3vh? What reasoning did you use?

But in general I think your font size settings are the way to go in the typographic world of things. It's just that you should also include/incorporate some sort of content width/content grid and font family into this expression. If we look at typographers' text block width table this should become the golden standard of setting readable font size based on text block width and font used. Viewport size may even be obsolete unless it's content uses 100% its width.

The usual typographer's bible (Elements of Typographic Style — Robert Bringhurst) has this table with width/font size/character count values

If I have to create a website for readability I try to base sizes according to my grid/text block size and this table or at least approximate on it.
