Not to be that guy, but it’s unreadable either zoomed in or in reader mode either horizontal or landscape on iOS. Colin, could the website be updated to the 2010s? :P
i assumed the parent did not know how to do that, i tried locally and it seemed to work, but i did not pay attention to the text
original:
on the left side of the url input field you'll find "AA"(the first smaller then the seconds), tap that
then, near the bottom of the pop-up menu you'll have "Show Reader", tap that
if you're not happy with the text as displayed then, you can go back to the "AA" menu and change the options
