The "html" element is the base element for the whole document, and is 16px by default. So by changing it to 20px, any base element text would become larger. But more relevant to this lesson is that in any child element that has a relative text size (expressed as a percent), that text would also become larger.

This is demonstrated starting around time index 4:53 in the video. He then also demonstrates that text items with fixed (pixel) sizes do not change.
