This document discusses using web standards to create interactive data visualizations for the web. It provides an overview of the JavaScript InfoVis Toolkit, which allows creating multiple graph and tree layouts using web standards and JavaScript. It also discusses upcoming improvements to browser engines and JavaScript that will further improve performance of interactive visualizations. Finally, it introduces WebGL and V8-GL as emerging web standards that bring hardware-accelerated 3D graphics to the web through JavaScript.
In the beginning, progressive enhancement was simple: HTML layered with CSS layered with JavaScript. That worked fine when there were two browsers, but in today's world of multiple devices and multiple browsers, it's time for a progressive enhancement reboot. At the core is the understanding that the web is not print - the same rules don't apply. As developers and consumers we've been fooled into thinking about print paradigms for too long. In this talk, you'll learn just how different the web is and how the evolution of progressive enhancement can lead to better user experiences as well as happier developers and users.
With great power, comes great responsive-ability web design. Responsive web design (RWD) will be demystified. Believe it or not, it's more than just media queries, although those will be discussed. It starts with proper UI design and application architecture, and then the dive into CSS - but not too deep! You don't have to be an expert to do RWD, but it helps to have some idea of what you are doing.
This document summarizes the history and evolution of web browsers and internet technologies from the early 1990s to the late 1990s. It traces the development of key browsers like Netscape Navigator and Internet Explorer. It also outlines the introduction of important web standards like HTML, CSS, JavaScript and XML. Major events included the commercialization of the web in the mid-1990s, the browser wars between Netscape and Microsoft in the late 90s, and the consolidation of online services providers toward the end of the decade.
After consulting with several companies on performance related issues, it became clear that one of the biggest performance issues facing websites today is the sheer amount of JavaScript needed to power the page. The demand for more interactive and responsive applications has driven JavaScript usage through the roof. It’s quite common for large sites to end up with over 1 MB of JavaScript code on their page even after minification. But do today’s web applications really need that much JavaScript?

This document provides an overview of techniques for developing high performance web applications. It discusses why front-end performance matters, and outlines best practices for optimizing page load times, using responsive interfaces, loading and executing JavaScript efficiently, and accessing data. The presentation recommends tools for monitoring and improving performance, such as Firebug, Page Speed, and YSlow.
This document provides an overview of HTML5, including its history, timeline, new features, and compatibility with browsers. Some key points: - HTML5 development is led by the WHATWG and W3C to standardize web applications. It simplifies HTML and introduces new semantic elements like <article>, <aside>, <header>. - New features include multimedia with <audio> and <video> tags, 3D graphics with Canvas, and offline/storage APIs. Forms are enhanced with new input types. - CSS3 adds animation, transitions and transforms. Performance improves with Web Workers and XMLHttpRequest Level 2. - Browser support for HTML5 features is tracked on http://caniuse
As browsers explode with new capabilities and migrate onto devices users can be left wondering, “what’s taking so long?” Learn how HTML, CSS, JavaScript, and the web itself conspire against a fast-running application and simple tips to create a snappy interface that delight users instead of frustrating them.
Slides from a brownbag tech talk at eBay. A holistic approach to web performance and intimate details on YSlow's points and grading algorithm.
The document discusses Adobe Experience Manager's capabilities for responsive web design. It provides an overview of responsive vs adaptive design and how AEM allows editing responsive layouts through a grid system. It then details how to set up responsive editing in AEM, including enabling the responsive emulator, layouting mode, and responsive grid. It also covers developing components for the responsive grid and leveraging breakpoints.
High Performance JavaScript provides techniques for optimizing JavaScript performance. It discusses how JavaScript execution blocks the browser UI thread, preventing responsive user experiences. It recommends limiting individual JavaScript jobs to under 50ms to avoid unresponsiveness. The document then provides techniques to improve load time performance such as dynamically loading scripts, and runtime techniques like timers and web workers to avoid blocking the UI thread during long-running processes.
Code at http://people.opera.com/cmills/css3book/css3-html5-dnrmn.zip. The browser vendors love them! The browser fans and cutting edge designers are producing some really remarkable stuff, but what do HTML5 and CSS3 really mean for you, the pragmatic designer on the street? If you sidle up to one of those guys and whisper "but what about IE6 support", they are likely to slap you in the face, or run away with their hands clamped over their ears, yelling "la lala lala, I can't hear you." In this talk, Chris Mills will have a look at some of the new features of HTML5 and CSS3 - new semantics, video, media queries, rounded corners, web fonts, drop shadows and more. He will show real world examples, and then look at how they actually perform on those shady older browsers we are often called on to support. He will then look at strategies for providing support for those older browsers, including using JavaScript, fallbacks, and progressive enhancement.
This document discusses HTML5 and provides an overview of its key features. It explains that HTML5 is not just the HTML language, but also includes related APIs that allow richer functionality. Some of the major areas covered include semantics and accessibility, rich internet applications using new APIs, and specific technologies like canvas, video/audio, web storage, and web workers. The document emphasizes that HTML5 is still evolving and aims to unify web development across browsers.
According to HTTPArchive.org the average web page is now larger than the original DOOM installation application. Today's obese web is leading to decreased user satisfaction, customer engagement and increased cost of ownership. Research repeatedly tells us customers want faster user experiences. Search engines reward faster sites with better rankings. Small, fast sites are cheaper to develop, maintain and operate. - Why has the web become obese? - What actions can developers and stakeholders do to combat their morbid obesity? - Are these actions expensive or hard to implement? This session reviews what customers want and how to identify your web site's love handles. More importantly you will learn simple techniques to eliminate the fat and create a healthy, maintainable, affordable web development lifestyle that produces the user experiences your customers want to engage with over and over.
The document discusses jQuery 1.9, 2.0, and the future of jQuery, noting that jQuery 2.0 drops support for older browsers like IE6-8 but is 12% smaller, and introduces 12 optionally excludable modules; it promises that jQuery 1.X will be supported as long as older IE browsers are relevant and that API equivalence will be maintained between 1.X and 2.X versions; and it invites attendees to join and contribute to the jQuery community.
