Having something weird.

I’m using html { font-size: 100% } and body {font-size: 62.5%} so I have 1em == 10px in CSS. I’ve done this several times before.

Now on my page everything works fine with the font-size, except for the font in the navigation in IE8 and IE7 (XP Mode)

I’ve fiddled relevant the HTML/CSS code here http://jsfiddle.net/gk4j9/3/

Using modernizr for browser ability switch for the gradients and shadows

Zoom is 100%
Text zoom is medium

The font-size is 2em, so should be 20px.
If I change to 1.8em in IE8 wih Developer Tools (18px) it looks quite the same as 2em in IE9 and other browsers

Answer 1

I figured it out.

In my XP Mode I do not have the Calibri font installed. So it uses a different font.

Bloody me!
