I hope I don't sound like a jerk saying this, but resizing the browser window is the key. I dunno why some people maximize everything on their computer - that's a really inefficient use of space.
I wish more websites wouldn't try to force formatting on me and just let me resize my window.
But you're probably on to something. I would be cool if the web browser would allow you to adjust the body size of the document without adjusting the window size.
I agree. Fossil mostly requires the use of CSS, but my own stuff I tend to not use CSS if I can avoid it, and often just write plain text files anyways (rather than HTML), which works well even if you are viewing them outside of the web browser, as well as with the web browser, too.
