Insert embedded stylesheet as block?

[Gnarlodious]

I'm hoping someone can explain this and give a tip what I'm doing wrong.

This doesn't work (simplified for readability):

<style type="text/css">
<SCRIPT TYPE='text/javascript' LANGUAGE='JavaS cript'>
if ( navigator.platf orm.substring(0 ,3).toLowerCase () == 'win')
document.write( 'body { font-family: Arial} ')
else document.write( 'body {font-family: Gadget } ')
</SCRIPT>
</style>

But this does:

<SCRIPT TYPE='text/javascript' LANGUAGE='JavaS cript'>
if ( navigator.platf orm.substring(0 ,3).toLowerCase () == 'win')
document.write( '<style type="text/css"> \n' +
'body{ font-family: Arial} \n' +
'</style>')
else document.write( '<style type="text/css"> \n' +
'body { font-family: Gadget } \n' +
'</style>')
</SCRIPT>

I've tried to write style text common to both if/else's in the HTML but it
won't work. Why is this? Does JS act differently inside the style tags?

JS does not act at all inside style tags. Inside style tags only style rules
make sense. It is a pity that we cannot test directly for the presence of
certain fonts on user's system, but why don't you simply write
body{ font-family: Gadget, Arial, sans-serif; }
so that the next is used if the first does not exist?

I guess I'll do that. Thanks for verifying what I suspected.
