If Android, try going into accessibility settings and set display size to maximum. Then see if you still like HN and many other websites with shitty unresponsive CSS.
IDK. In my case, instructions are much more readable in osmand while driving. Better readability is kinda the whole reason why such a setting exists. I certainly hope I'm not the only one trying to break my own work by adjusting a11y settings in the os. Computers are meant to support people, not the other way around.
