[SalesForce] Visualforce and CSS – nothing

I can't get any CSS to work at all. Am I missing something extremely obvious?

EDITED to include URLfor

<apex:page standardStylesheets="false" showHeader="false" >
    <apex:stylesheet value="{!URLFOR($Resource.cssSampleGREEN)}"/>

    <h1>test content for color output</h1>
</apex:page>

If I have a static resource called cssSampleGREEN which is the COMPLEX CSS code

<style type="text/css">
h1
{
    color:#00cdcd;
}

I should at least have green output to my h1 text but that does not happen, I just get the below. What is my error?

It's fine - just take the <style> tags out of stylesheet.

Static resource like this :-)

h1
{
    color: #00cdcd;
}
