My eyes cringe at Web pages with light-on-dark type. Dark-on-light was good enough for Gutenberg, and it’s good enough for me.

Now there is a solution: a Java script in the form of a toolbar bookmark that lets you flip headache-inducing light-on-dark pages to the way that Johannes intended. (Thanks, Kelley.)

For the bookmarklet, just scroll down to the box marked “Update,” and drag and drop.
