Thank you.
The document provides an overview of how a browser works by breaking it down into key components and subcomponents. It discusses the user interface, browser engine, rendering engine, networking, JavaScript interpreter, UI backend, data persistence, and web APIs that make up a browser. It then dives deeper into specific subcomponents like the HTML parser, CSS parser, DOM, rendering tree, layout and reflow process, and event loop. The document uses diagrams and examples to illustrate how each component interacts and the main flows and processes involved in rendering web content in the browser.
Browsers work by parsing HTML and CSS to construct a DOM and render tree, laying out elements and painting them to the screen. The main components are the user interface, browser engine (which handles networking, JavaScript interpretation, etc.), and rendering engine. The rendering engine constructs the DOM from HTML and CSSOM from CSS, builds the render tree by combining them, then lays out and paints elements to display the final webpage. Optimization focuses on minimizing critical resources, path length, and bytes to speed up the initial render.

The deep web refers to content on the internet that is not indexed by search engines like Google and makes up an estimated 500 times more information than the surface web. It exists because search engine technology cannot index dynamically generated or password protected pages. The deep web can be accessed through anonymity software like Tor and contains both positive resources like educational papers as well as illegal activities due to anonymity. As more data is created, challenges remain for search engines to effectively index the deep web.
The document discusses key concepts in web technology including markup languages like HTML and CSS, scripting languages like JavaScript and VBScript, and how they are used to create dynamic and interactive web pages. It also provides an outline of two course modules that will introduce students to these concepts and languages and how to use them to add functionality and validate forms. Additionally, it summarizes the history and development of the internet and world wide web, defines common web terms like URLs, HTTP, websites, web browsers, and email.
The Document Object Model (DOM) is a standard for representing and interacting with objects in HTML, XML and SVG documents. It defines the logical structure of documents and the way a document is accessed and manipulated. The DOM represents the document as nodes and objects, which can be manipulated programmatically by JavaScript to change the document structure, style and content. It allows dynamic access to and manipulation of page content that is useful for building interactive web applications. The DOM specification is developed by the W3C and provides a platform- and language-neutral interface that can be used across different web technologies.
The document summarizes the history of web design from the early 1990s to the present.

This is the Slide I used at the Lagos Web Meetup where I talked on Web Development and Web Development Technologies.
It outlines most of what was discussed at the meetup.
The document discusses the history and components of the World Wide Web. It explains that Tim Berners-Lee invented the World Wide Web in 1989-1990 at CERN as a way to exchange information using hypertext documents accessed via the internet. The World Wide Web is constructed using HTML and the basic steps to create a web page are to write the HTML file and upload it to a web server. The internet and World Wide Web are different concepts - the internet is a global network of interconnected computers while the World Wide Web is a system of hyperlinked documents that runs on the internet.
These slides describes about rendering engine, types of rendering engine and how Webkit rendering works.
A rendering engine (also called layout engine or web browser engine) is a software component that takes marked up content (like HTML, XML, image files, etc.) and formatting information (like CSS, XSL, etc.) and displays the formatted content on the screen.
The JavaScript programming language is a multi-paradigm language that is misunderstood due to its name, design errors in early implementations, and use in web browsers. It is a functional language that uses objects, prototypes, and closures. Values in JavaScript include numbers, strings, Booleans, objects, null, and undefined. All other values are objects.

How Browsers Work -By Tali Garsiel and Paul IrishNagamurali Reddy
The document provides an overview of how web browsers work behind the scenes. It discusses how browsers parse HTML and CSS documents to construct DOM and render trees, and then layout and paint content to display it on the screen. The main steps are: (1) Parsing HTML to create a DOM tree, (2) Parsing CSS and applying styles to construct a render tree, (3) Calculating element positions through layout, and (4) Painting elements to the screen. This process occurs gradually as content is received from the network to improve performance.
This document provides an overview of using HTML5 Canvas for game development. It discusses how Canvas allows 2D drawing directly in the browser using JavaScript. Common Canvas methods like fillRect() and strokeRect() are used to draw shapes. Canvas is useful for games, animations, and data visualization. Optimization techniques like requestAnimationFrame can improve game performance. Popular JavaScript libraries that are useful for HTML5 games include Box2D for physics and SoundManager2 for audio. The document provides examples of simple games built with Canvas in a short time period, such as a 2-week Mario game project. It concludes with further resources for learning HTML5 and Canvas game development.
GWT - Building Rich Internet Applications Using OO Toolsbarciszewski
Google Web Toolkit (GWT) allows developers to build rich web applications using Java instead of JavaScript. It compiles Java code into optimized JavaScript and HTML that runs across browsers. GWT provides widgets, remote procedure calls, internationalization and other tools. It allows code reuse on both the client-side and server-side. While the compile can be slow, GWT offers advantages like full Java tooling, one codebase, and optimized browser code. The speaker demonstrates a sample GWT application and discusses how StudyBlue uses it.
Browsers render web pages through a multi-step process involving parsing HTML, computing styles, constructing frames, layout, and painting. Key optimizations include minimizing payload size through techniques like compression, lazy-loading content, reducing reflows and repaints caused by DOM manipulation, and optimizing JavaScript execution through techniques like proper scoping and reducing property access in loops. Modern developer tools can help identify performance bottlenecks.

● Display content according to HTML and CSS
specification. (W3C Specification)
● Today, mostly browser do not follow all w3c
specification.
5. jghj
HTML(4 or 5 ) specification does not
define UI element. A browser must
have, like file-type input variable.
13. jghj
Browser’s Component
1. The user interface:
a. Every part of the browser display, except the window.
b. The address bar, back/forward button, bookmarking
menu, etc.
2. The browser engine:
a. Bridge between the UI and the rendering engine.
14. jghj
Browser’s Component
3. The rendering engine :
a. Parse HTML and CSS.
b. Display parsed content on the screen
4. Networking
a. Network calls such as HTTP requests
b. Platform-dependent
15. jghj
Browser’s Component
5. UI backend:

● Beyond above things, we need extension/Add-one/Plug-ins
● Rendering Engine
○ Chrome and Opera : Blink
○ Chrome (iPhone) & Safari : WebKit
○ Firefox : Gecko
○ IE : Trident
19. jghj
Rendering Engine Main Flow..
Build Dom Tree
# Get data from network Layer.
# Parse HTML.
# Create DOM nodes (Build by Elements).
# Content Tree/ Dom Tree.
# Resource(CSS) loading during parsing
Build Render Tree
# Parse CSS (Inline +External).
# Dom Nodes + Parsed CSS Info.
# Build Render Tree.
# Display start on Browse-Window.
Painting
# Each node Painted.
# Use UI backend Component.
Layout Process
# Given coordinate to each node where they will
appear.
# Always start from root node(0,0).
# Recursive process.
21. jghj
● Execute script immediately when parser reach at
<script> tag.
● If the script is external then first, the resource must be
fetched from the network.
● In both the above cases, Parser will be on hold until
script is executed.
