No one is modifying this website, the problem is with your browser on your computer which isn't wrapping/justifying the text conveniently for you to read.

The Javascript code shown implemented as a Bookmarklet is telling your browser how to format and justify the text if you want to implement it on your browser.

Anyway I've broken up the longish Javascript text strings with some carriage returns and you could always use the Zoom in and Zoom out functionality on your browser.

You shouldn't have a problem if using Internet Explorer, Google Chrome or Opera.

The difference is somewhat like using notepad instead of wordpad on a windows OS.
