On my ipads, the text on this site is too small in default form (when clicking in) … however, a slight two finger touch on the screen enlarges text easily but of course … devices differ and it might not be so straightforward for you.

That would indeed be a pain and I’m conscious of that, esp. for our older colleagues … maybe 5% enlargement might be perfectly legible.

The solution is to use two fingers if a touch screen to enlarge or if with a keyboard and mouse … Ctrl + scrollwheel. H/T Microdave, who adds: “Out of curiosity, I tried holding down the Ctrl key and then briefly pressing the minus or plus key, and found this varies the text size as well.”
