How A Page is Designed?

how a page is designed?

To design a site you need to know how to use Photoshop, and code it with the html language

You can also use Gimp which is free (http://gimp.org/)
if you don't have the Money to pay for Photoshop ;-)

Or you can use oneof many free website templates.... or you could...
I think first of all we need to have a bit more specific information about your degree of knowledge and the project you are planing.
As more specific your questions are, as more likable you will get an answer, you could deal with and make use of.

Knowledge of the person:
Post oneliners and get a link from the signature ...

Yes Giorgos, my first thought too, but than there wasn't a signature... ?
Anyway..

That's right there is no signature or even a link from his profile

a webpage is designed with any graphics software mainly photoshop and then sliced and coded.
