These sites are XHTML 1.0 compliant and follow the standards as approved by the W3C. They make extensive use of CSS 1 and CSS 2 (CascadingStyleSheets) to create a completely tableless layout, allow faster rendering and interoperability with clients, such as mobile devices.
All contents should be painlessly browseable with common browsers equal to or above generations 4 of Internet Explorer or Mozilla/Netscape. You may miss certain layout beauties and experience unpredictable behaviour when using Netscape 4, best advice here is to avoid using this buggy creature.
Anyway, if you experience any severe pain in browsing or viewing contents don't hesitate to contact 1A-N via frameworking@1a-n.net.
