Graphic Layout : Website realized on Macromedia 8 Template, personally modified in XHTML 1.1 code, I used DW8 and Notepad 3.7++ for XHTML and Topstyle 3.12 for CSS.
Layout-Code : Layout is tableless to grant the accessibility to all device( such as mobile device), and it's also valid XHTML 1.1 checked with online validator by W3C and offline using Firefox extension Html Tidy validator. 
Compatibility : Website tested with the following browsers: 
Linux : Tested on Gentoo(and Gentoox :D) distro and KDE interface with Firefox 1.07 and Konqueror 3.4.x, on Fedora distro with Firefox 1.07 e 1.5.
Macintosh : Tested on Safari 1.2, 1.3(OSX 10.3) and 2.0 (OSX 10.4)
Symbian : Tested on Mobile Opera version 8.60 for Nokia N70
Windows : I decide to not use hack for guarantee compatibility for Ie 5.5 and before, website tested with Opera 8.5x/9 final, Firefox 1.07 and 1.5.x, IE 6.0 and IE 7.0 beta2.
Browsers suggestions: Obviously Opera, Firefox e Safari, Ie 6 is not entirley compatible with this website because some basic CSS proprierty are not supported by this browser (ex:min-width), Ie7 maybe will be better as Microsoft write in this article.
Accessibility :This website respect Wcag 1 and partially Wcag 2(AA) specifications , check was made with online validator , as soon as possibile i will manual test with a screen reader like Jaws. (all suggestions are wellcome )
