Hello!

Can you write me if white text on the main page takes part in indexing by
robots? I mean white by setting the css style="color:white", the same as
background color of my page.
If so, is it possible to place some long text which is not visible on the
page but is placed on the web page. I would like to do so to take this text
into account by robots. Which html tag and which way should I use then?

Thank you
Marcin
