This document provides an overview of HTML5 and what's new in the latest version. It discusses new semantic elements like <header>, <nav>, and <article> that improve document outlining. It also covers new multimedia features like native audio and video playback without Flash, as well as 2D/3D graphics using <canvas>. Other additions include new form controls, multiple file uploading, and geolocation. While HTML5 brings many new features, it is an ongoing evolution of HTML rather than a completely new language.

This document summarizes Christopher Schmitt's presentation on adaptive images in responsive web design. It discusses using feature testing versus browser sniffing to determine the appropriate image to serve, including testing browser width, screen resolution, and bandwidth. It then covers various techniques for serving adaptive images, such as using .htaccess files, the <picture> element, srcset attributes, and JavaScript libraries. It emphasizes using a mobile-first approach and progressive enhancement to provide the best experience for all devices.

The average website loads over 1.5MBs of content per page, making over 75 requests. Many popular websites are serving over 5MBs just to load their homepages. And these numbers represent measurements taken AFTER compression is applied. The full weight of many popular websites is pushing 20+ MBs these days. In an era where performance truly matters to the end user experience, web developers need techniques to help curtail this bloat in data down the wire. No matter how well you optimize, there is no better way than to delete things you do not need. How does one determine what is essential to the user experience and what is not? One answer Chris posits is to develop a hyper-lightweight version of your website which will provide critical insights into your specific performance priorities. This is a process that he has leveraged on many projects, in particular at YouTube to reduce the size of the video watch page from 1.5MBs to 100KBs. In this talk, Chris will take real-world web pages and show techniques for dramatically reducing their page weight and for identifying areas to optimize, while outlining the key steps to doing this well.

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.

Progressive downloads and rendering allow content to be delivered and displayed to the user incrementally to improve perceived performance. JavaScript should be placed at the bottom of the page to avoid blocking. CSS can block rendering so should also be delivered non-blocking when possible. Techniques like flushing output, non-blocking scripts, and data URIs can help deliver content progressively. MHTML and preloading can help optimize delivery across multiple HTTP requests. The overall goal is to start displaying content as soon as possible while content continues downloading in the background.

This document provides an agenda and overview for an HTML5 and CSS3 workshop. The agenda includes explaining differences between HTML5 and XHTML, building with HTML5 elements like <header>, <nav>, <article>, <aside>, and <footer>, bringing back semantic HTML tags, figures and captions, editable elements, drag and drop, HTML5 metadata like microformats, and page structure. It discusses syntax changes in HTML5 and introducing new elements and attributes to improve semantics and accessibility.

1. The document discusses the steps needed to deploy a web application including choosing a web host, domain name, web server, database, and technologies. 2. It recommends using a virtual private server or shared web host to avoid maintaining physical infrastructure, and choosing technologies like Apache, MySQL, and Python/Django based on your specific application needs and comfort level. 3. Key steps include buying a domain name, configuring the domain to point to your web server's IP address, setting up the Apache web server with mod_wsgi to run Django projects, and configuring Django to use a MySQL database.

Lets look at an example of what a performant website can look like. This discuss what concepts should we be considering when looking at website performance. Next we will go over two areas pertaining to website performance: 1) website performance tweaks that you as a web developer can directly make 2) website performance tweaks that you may have to work with your hosting provider or IT department to achieve

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?

It's been 6 years since the term Responsive Web Design (RWD) was coined and today is difficult to see new projects without implementing it. But this time has allowed us to see the implementation can be even more important than the technique and the theory. The RWD covers from the performance to the implementation of patterns and "standard" behaviors to improve usability. In this session reviewed tools, techniques and concepts to improve our projects: - Performance and best practices - CSS structuring and optization (BEM, SMACSS, etc.) - Fixed-Pixel vs rem, em and % - Responsive images. Drupal non-Drupal solutions and SVGs - Asynchronous Javascript loading - Typography in a responsive environment and FOUT, FOIT effects - How proxy-based browsers like Opera Mini can affect, and how accessibility and Progressive Enhancement can help. - Beyond the Mouse: Touch and keyboard events - Using RWD patterns

The document provides 14 tips for optimizing website performance based on the 80/20 rule. The tips include minimizing HTTP requests by combining files, using a CDN, adding caching headers, gzipping files, optimizing CSS and JS placement, avoiding redirects and duplicate scripts, and making Ajax cacheable. Following these best practices can significantly improve page load times by reducing network requests and making better use of browser caching.

Web performance optimization can be done at three levels - general, server-side, and technology. At the general level, techniques include minimizing HTTP requests, optimizing images, minifying files, avoiding redirects and empty sources. Server-side optimizations involve techniques like content delivery networks, cookie-free domains, caching, and gzip compression. At the technology level for dynamic sites like Joomla, optimizations include flushing buffers early and optimizing database queries. Performance can be measured using various online tools.
