Where to place mobile css

Hi guys,

Quick question: Where do you place the mobile only css?

I thought it went like this:

- global.css: Here you place global styles and all mobile styles
- normal/narrow/wide: Here you place styles for normal/narrow/wide. You just override the mobile styles.

But this doesn't seem to be the case. (Because some css in global.css isn't working on mobile)

So is there a sepperate css file for mobile-only css?

I tried adding alpha-mobile.css (in the folder + info file) but the css is affecting all pages...

Help would be appreciated. :-)
