It's funny, I use Firefox on my phone and both of the examples ("normal" and "balanced") look exactly the same to me[1], with the line break between "savvy" and "businesses", but I gather from the text that they're not supposed to look the same. I get that the article is talking about blink browsers but it's also assuming that everyone has one. I suppose they should have put an image there instead of having the browser render it.
