it is not locked to the user setting. the following screen is one of my sites on my w2k3 server, ie7, without changing any settings in the browser or os:
you can see the text is antialiased, though its not as smooth as the previous example from macos.
the following is the css code that styles the text on that site:
Code:
body {
font: 13px "Lucida Grande", Verdana, Arial, sans-serif;
line-height: 1.22em;
}
select, input, textarea {
font: 99% arial,helvetica,clean,sans-serif;
}
pre, code {
font: 115% monospace;
}
so i guess it throws the unit idea out of the window. experiment and see what happens.
personally though, i would not use flash or images for text, especially when the only reason is anti aliasing.
