Parsing an HTML document into a DOM is defined by the HTML Standard. The DOM is a browser's internal representation of the page as well as the data structure and API that web developer can interact with via JavaScript. When the renderer process receives a commit message for a navigation and starts to receive HTML data, the main thread begins to parse the text string (HTML) and turn it into a Document Object Model ( DOM). Figure 1: Renderer process with a main thread, worker threads, a compositor thread, and a raster thread inside # Parsing # Construction of a DOM The renderer process's core job is to turn HTML, CSS, and JavaScript into a web page that the user can interact with. Compositor and raster threads are also run inside of a renderer processes to render a page efficiently and smoothly. Sometimes parts of your JavaScript is handled by worker threads if you use a web worker or a service worker. In a renderer process, the main thread handles most of the code you send to the user. The renderer process is responsible for everything that happens inside of a tab. If you'd like to dig deeper, the Performance section of Web Fundamentals has many more resources. Since there is a lot happening inside of the renderer process, this post is only a general overview. ![]() Renderer process touches many aspects of web performance. In this post, we are going to look at what happens inside of the renderer process. Previously, we covered multi-process architecture and navigation flow. We have recently released the latest update to layers scrollable layers! You can add another dimension of sophistication to your prototype by using long menu panels or modals which you can scroll to see the full content.This is part 3 of 4 part blog series looking at how browsers work. Please note that the layer to layer feature only allows one layer to be open at any time. You can see an example of the layer-to-layer feature in action below. Select another layer image from the menu at the bottom > click on the 'layer' button again.Open the layer image itself within the editor > click and drag to draw a hotspot on the image.Select the layer image from the menu at the bottom > click on the 'layer' button towards the left of the menu.To add the layer-to-layer feature to your own prototype: Now you've got the basics, lets take it a step further by using our layer to layer feature: You can see an example of layers in action in this prototype: Position your layer by dragging the image in the editor, you can also change the opacity and background colour.The layer an image option on the left will become available, click the button.In the image selector pop up, select the destination for your hotspot.Once the Editor opens, click and drag anywhere on the image to draw a hotspot.Select any image in your project and click view.It's perfect for adding realistic overlays such as:Īll you need to do is upload the layer(s) directly to Marvel, as you would any other screen. Layers allow you to add elements over the top of your screens as hotspot destinations. ![]()
