I read a few days ago that Google are unlikely to analyse CSS directly
(never assume this won't change in the future), just as they index images
using separate crawler that get employed.
Google will nonetheless be able to 'see' CSS if it is embedded in the HTML
file rather than in auxiliary files. I was also made aware of the fact
that <font color="#eeeeee">, for example, atop white background can be de-
tected and interpereted as hidden text. Whether it's a semi-automatic ap-
proach involving human reviewers, I am not too sure. It seems like they
can afford manual labour these days. They sure can.
Having mentioned colour tricks, I am not sure to what degree this can be
automated. Pruning out the obvious is easy, but your average Webmaster
will adopt some streetsmarts. White background can be injected using a 1X1
plain white image (a white pixel tiled), which is reminiscent of the
transparent pixel used for spying.
