120 — font-size defined twice

case study — FireFox / Chrome
different behavior.

A font-size is defined twice:
  main.css:7      font-size: 10px;
  main.css:85     font-size: 10pt;

And both FF, Chrome have (user agent)
  h3 {
    font-size: 1.17em;
  }

The two screen shots below are showing that
  Firefox choose the last def, and set font-size:13.33pt
  Chrome choose the first def, and set font-size:11.7pt

Note:

• font-size @main.css:85 is defined in a media query block.
• both screen have a device-width >1000px.

  @media screen
  and (device-width > 1000px) {
    body {
      font-size: 10pt;
    }
  }
