Inspired by the original CSS proposal, which includes “weighting” of each rule or style sheet, and generates a weighted average:
/* user styles */
html { font-size: 16px 60%; }
/* author styles */
html { font-size: 100px; }
I’ve given the user/user-agent
root font-size
a weight of 60%,
and my own
<code>100px</code>
font-size
a weight of 40%.
