How Web Browsers Build Pages

As an online marketing consultant and website development professional, I look forward to reading the series of articles “From URL to Interactive” recently published by our friends at A List Apart:

Our whole industry depends on our faith in a handful of “black boxes” few of us fully understand: browsers. We hand over our HTML, CSS, JavaScript, images, etc., and then cross our fingers and hope they render the experience we have in our heads. But how do browsers do what they do? How do they take our users from a URL to a fully-rendered and interactive page?
