Break up long lines for easier legibility and printability
Some of you have noticed how irritating it is to code when you have lines that go off the edge of the screen.
One of the cool things about HTML is that you can hit
anywhere in your code, and the browser will ignore it.
This means that if a line is running off the edge of the screen, you can break it up into one phrase or sentence per line in your code without it affecting the look of how your web page is displayed.
This makes it much easier to follow the flow of code, and has the added bonus of not cutting things off or shrinking everything when you print.
There is such a thing a "wrap long lines" in your text editors, but that does not help you with printing.
