How to use this EmChart to get perfect font sizes in ems?
What is the purpose of this chart and how to use? 开发者_如何学JAVAhttp://aloestudios.com/tools/emchart/
Given a current font size of the-row-headings, and a wanted font size of the-column-headings, set the font size to the number of ems at the point of intersection.
Of course, you can't know what the user has their default font size set to (although many people assume it is 16px) so it is largely useless.
