If you zoom a picture up from its native px size, it will soon be
noticeably fuzzier. We were at some point in the thread talking pictures
of text not html text. So what I am saying certainly applies to this. If
you are not following this part, let me know and I will explain more.

OK, now lets look at proper html text, (not specified in pixel
font-sizes - to avoid a side issue to do with Windows Internet
Explorer). Not gifs, not jpgs or pngs but simply text typed into html
elements.

Most good browsers allow one to make the text bigger or smaller to suit
oneself. Either on a tactical basis, page to page and using menu and/or
keyboard commands or on a more global basis via preference settings or
user stylesheets. These latter allow a user to avoid suffering
impossibly small fonts as well as slightly uncomfortable ones. The
browser simply overrides any font style settings of the author of the
site and substitutes the user's preferred. A pretty wholesome thing, I
hope you will agree.

Take a look at http://store.apple.com/us (to take a Mac example) in
Safari 2 or any browser that does not zoom the page but just zooms the
text. The text stays crisp no matter how big it gets. Never mind that
some of the text disappears or the design breaks (*that* is another
matter entirely). It stays crips because the browser draws up real text
from your fonts on your machine and uses the vector type maths to do so.
That is the magic of real fonts, they can be scaled and remain crispier
than chips.

Now look at it in Opera and zoom it up and it gets blurry. There is
nothing to explain, it gets blurry and it does so in pretty well the
same way as pics do when blown up beyond their native pxs. There is no
special font maths involved here. The font is treated as just a set of
pxs and is enlarged by a crude(r) browser algorithm to be bigger. The
blur is then the general blur that results from machines not knowing
what is important and what not when blowing up pics. Even a classy image
program like Photoshop does poorly when blowing up a pic, browsers are
not any better.

Roughly this.
