Re: viewport declaration

[Karl Berry]

    I will certainly add it but could you explain what difference it
    makes?  Does this fix the "font boosting" issue?

It should help (as noted), yes. The practical result is that mobile
devices skip the step of laying out the page with a large size and then
shrinking it, but just render it according to the pixels available. (The
way it should have been done in the first place.)

I don't know much about it, or mobile in general. A friend pointed it
out to me. Here is some info about it:
https://www.w3schools.com/css/css_rwd_viewport.asp
https://developer.mozilla.org/en-US/docs/Mozilla/Mobile/Viewport_meta_tag

In my experience, for straightforward text pages like makeinfo output,
this viewport decl by itself is enough to make the difference between
"unreadably tiny" and "basically usable" on mobile, without needing to
also insert a bunch of css. --best, karl.
