I have been using (an older version of) Tufte CSS on my blog[0] for years now. I had to tweak it quite a bit before I thought it looked OK on both phones and tablets but I really think it does work well for the longer-form posts I was originally aiming for.

I would add more left and right padding.

It's my website and I'll do what I want! :)

More seriously, you bring up a good point about form factors. I imagine you are reading my site on a cell-phone. On these devices I purposely made the page width more-or-less fill the width of the screen to fit more text in at a readable font-size.

This used to be a reasonable choice because cell phones all had bezels. Now that many phones have screens that extend all the way to the edge of the device, pages like mine look weird as the text bleeds underneath the users fingers.

Just another example of how it is difficult to design a page that looks good on the multitude of devices that people use these days.

I'm probably not going to change it though.
