Merci d'avance !
NetFront uses its own custom layout engine. It is not based on the
layout engines of Internet Explorer, Firefox, Opera, Safari, or
Konqueror, so my standards support tables currently don't include it.
There are many mobile browsers that use custom layout engines, and I
can't test all of them. If PSP had more market share, I might add
information to my tables, but for now I'm going to focus on other
browsers and other sections of Web Devout.
Here are some compatibility tables created by MacEdition:
