Multiple CSS #media conditions don't seem to be working - css

Question

I'm trying to modify just a few classes in my CSS for different screen resolutions, I'm aiming to have:
The default applied CSS for 1200+ width,
A media query embedded in the css for resolutions between 601 and
1199 px, //This is what's not working
A media query embedded in the css for resolutions 600px and below
When i use a single width condition, for example #media screen and (max-width: 600px) { , the css is applied as it should be.
However when I try #media screen and (max-width: 1199 px) and (min-width: 601){ the style never gets applied..
I've tried swapping the order of these conditions and also just having #media screen and (max-width: 1199 px) on the basis that the 600px rule will override it afterward but for some reason it just doesn't seem to work. Just to be clear, i've either got the default styling or the 'max-width: 600px' style when i shrink the screen to less than 600px, i can't seem to get a style applying for the middleground.
Any obvious mistakes in my CSS?/suggestions? Would be appreciated!
I bunged my html and css into a jsfiddle for anyone who wants to see for themselves http://jsfiddle.net/X6cZ7/3/ (Observe the navigation bar li items as you drag the view for the website, they change style at <600px but should also look red (for testing) at <1199 yet they dont) Only testing on Chrome at the mo, in case that's relevant.

Answer 1

In your css there is some typing mistake, hence its not working, please check below
Not Correct
#media screen and (max-width: 1199 px) and (min-width: 601){
}
Correct one
#media screen and (min-width: 601px) and (max-width: 1199px){
}
EDIT:
There shouldn't be any spaces between the value and unit, i.e. 1199 px is wrong it should be 1199px.

Answer 2

Yo have forgot to put "px" in max-width: 1199. I think this is creating problem.
Anyways, You should code for mobile first & keep on coding for larger resolutions.
