D'lite Your keyboard/mouse movements can be intercepted by JS which in-turn can manipulate the DOM. The rendering engine is the heart of the browser. Different engines (WebKit vs. Gecko) can produce different outputs. You can learn more here: https://developer.mozilla.org/en-US/docs/Web/API/Document_Object_Model/Introduction

What do you mean by non visual? Almost any element can be programmed to have a visual effect. Do you mean elements that don't effect the DOM like heading tags?

The DOM is your browser's output from the code you wrote.

D'lite Not really. Lots of things can affect the DOM. The DOM is basically how the page is rendered in real time. Mouse movement, JS, keyboard input, the rendering engine, and the browser's error correction can affect the DOM.

D'lite The DOM can be manipulated by JS. The popular jQuery was actually built for the very purpose of making DOM manipulation easier.

Семён The rendering engine takes the markup and converts in into a map of the website, this is call the DOM. With the map it then draws everything on to the screen based on things like the CSS rules.

document object model, you're basically treating the webpage as an object with properties

Семён No sir, DOM just shows you how elements are related to each other in your website.. It's HTML and mostly CSS that determines what your websites look like

Umm,guys, how does work the rendering engine? I feel like I still haven't got it... A rendering engine interplays with DOM,right? But in what way?
