### Optimize base font size setting while using `rem` for Global Sizing
For better calculation from `px` to `rem`, setting the base font size at the root(`html { font-size: 62.5%; }`) is even better.
Since the default size of html is `16px`, and 10/16 equals to 62.5%。Then `14px` can be converted to `1.4rem` while at the same time allowing user to change the default size.
