Several folks asked me about the flowchart of the IE rendering modes that I showed in one of my sessions on GeekReady Asia. I share it here so it is easier for everyone to find it. The flowchart was created by Henri Sivonen. He shared the flowchart in his great article: Activating Browser Modes with Doctype. In this article, he explained how browsers, not only IE but also other major browsers, chose the rendering modes according to the Doctype. Thanks to his excellent work.
