Right.  But what you're saying makes no sense to me.  Browsers' default 
font sizes are set in points.  So if I say "9pt" or "11px" or "1.75em" 
or "80%" it still compares that size against the "12pt" that the browser 
thinks is its default.  When you "zoom" a page, a percentage is applied 
to that calculated difference.  None the chosen method of portraying the 
info should have a bearing on the ultimate outcome of the file size. 
I've never seen a browser work other than this.

But I'm not scaling by percentages.  I want a rather specific font size 
that matches against images or the rest of the stuff on my screen 
(outside of the browser window).  For a lot of my stuff, I'd *much* 
rather that the browser be rendered incapable of changing my font sizes 
(esp. if I specify pixel sizes).  It doesn't.  Heck, not even all 
browsers render things the same size when you specify them in pixel 
heights, esp. if you're comparing normal text with form input fields).

When I say 12pt, I mean 12pt.  If I say "100%" but haven't specified a 
font size, I don't know what size "100%" is in relation to.  What if I'm 
trying to do something like the search box in mythweb, where I need to 
match it and some other text against the height of some images -- I 
don't want to say "100%" and have that be 100% of 24pt.  Each of the 
units in css was created for certain instances -- I can see how handy it 
might be to define sets of fonts to be in relation to each other (eg. 
header at 150%, text at 100%, footnotes at 50%), but in all 
circumstances, they go back to either the point-size specified in the 
browser or css defaults, or the pixel size specified in the css.

my "system" is a collection of about a dozen boxes (mac+linux+windows at 
home, linux+windows+windows+... at work).  Granted, I don't do mythweb 
testing at work, but everything else I play with follows the rules I 
outlined above.

Or maybe you're setting your default sizes for your browser in points, 
rather than using "zoom" like its intended for?

I just don't see what I can do that would satisfy your desire for a 
default-small font and still have it work with everyone else.  I specify 
9pt because it's small in relation to the default 12pt.  If I specify 
75%, it'll still be the same size in your browser as it is at 9pt.  I'm 
not about to go leaving out a global font size, since I want a specific 
look (12pt or so for default), and many IE browsers are defaulted to 
14pt which is just huge.

Odd.  It's very clear for me.  I just made it a little brighter -- 
hopefully that will help.
