 In order to render a web page, or re-render it upon some visual style change, the browser needs to go through four classic steps. There's style, where it would calculate the styles that apply the elements that needs to be calculated first. Then there's layout step, or layout stage, where you generate the geometry and the position for each of those elements. Then there's paint, where you fill out the pixels for each element onto layers. And then there's composite, where you draw the layers onto the screen. Why do I want to do this skit on stage at some point? I know. There should be like a little, there's many cartoons. I feel like there's a lot of articles about how to do this. There's lots of doodles, but I want to see a person do it. You have the power, and you have the equipment. Touche, I suppose I shall then.
