Responsive and Fast

The document summarizes Christopher Schmitt's presentation at RWD Summit 2014 on adaptive images in responsive web design. It discusses using feature testing over browser sniffing to determine screen resolution and bandwidth. It presents techniques like srcset, picture, and JavaScript solutions to serve appropriately sized images. It also covers workarounds like background-size, SVG, and font-based solutions when native techniques are not supported. The focus is on building responsive images that scale with the device and load quickly.

The web doesn't stop at the desktop anymore. Our image assets need to do more than look good in one context. In this talk, I look at how images like JPEG, GIFs, SVG, Icons, Unicode, and more can be used in a multi-device environment.

Smartphones and tablets not only contain more computing power and better browsers than the computers that started the Internet economy. They also have better displays, which demands more of us when we use images. This session will work through tips and tricks to develop future friendly images in our sites and apps.

Web accessibility is a crucial component of how we construct our websites today, some with legal requirements to ensure our websites cater to clients of all abilities and disabilities. But how much do we actually know about web accessibility, it's implications and it's implementation? How much do we know about the accessibility of the latest technologies like HTML5 and WAI-ARIA? And can we use these now? Once you begin to think about web accessibility and accessibility in general, you start to see the world in a very different way. In this talk, Tady Walsh, will take us through website accessibility, starting at the very beginning and will continue up to and including today's technologies. He will discuss, not only how to cater for the various types of disabilities our website visitors may have, but also the way we as developers and designers should be thinking about website accessibility, in every step of our work. Bio: Tady is a project manager and information architect with Arekibo Communications. With a background in front-end development, he has been working and thinking about web site design and development for the past 15 years. He's a vocal supporter of cool design, good user experience and considerate development methods. His thoughts and opinions can be found on twitter as @tadywankenobi, on his website at http://www.tadywalsh.com and also on Arekibo's blog http://blog.arekibo.com.

Websites are viewed on all kinds of devices, in all kinds of browsers. In this presentation, I explain how you can adapt your site to these different environments, using modern browser hooks and techniques. I cover the various aspects (and some gotchas) of the viewport mechanism and media queries, and shed a light on how new CSS3 properties allow you to optimize images and videos for multiple screens.

This document discusses responsive images and various techniques for implementing responsive images, including: 1. Using .htaccess files to serve different image sizes based on screen resolution. 2. Implementing the <picture> element and srcset attribute to serve different image sources based on media queries. 3. Using JavaScript solutions like HiSRC to programmatically swap image sources based on screen properties like pixel density and connection speed. 4. Various workarounds and tricks for responsive images, including using background-size: 100% for images, optimizing images as SVGs, and using font-based solutions.

Neev Technologies is a software development company established in 2005 with development centers in Bangalore and Pune, India. It has offices globally including the US, Sweden, India, and Singapore. Neev specializes in responsive UI design using CSS media queries to detect screen sizes and reposition or remove content blocks to optimize the layout based on the viewing device. CSS media queries allow defining CSS rules that apply when certain media query conditions are met, such as screen width, to implement responsive design.

This document introduces several CSS3 features including CSS3 PIE, @font-face, border-radius, border-image, rgba, box-shadow, text-shadow, linear-gradient, and columns. For each feature, it provides a brief description, examples of CSS code to implement the feature, and the browsers that support it. It also includes links to additional CSS3 resources.

The document discusses techniques for optimizing responsive web design for mobile devices, including downloading and hiding/resizing unnecessary elements based on screen width, using lightweight JavaScript libraries conditionally, responsive images with srcset, and serving different content for mobile using server-side device detection. It provides examples and links to resources for implementing these techniques.

This document summarizes Christopher Schmitt's presentation on adaptive images in responsive web design. The presentation discusses: 1) Using feature testing and media queries to determine screen width and resolution instead of browser sniffing 2) Techniques for serving adaptive images, including .htaccess redirects, srcset, picture, and JavaScript libraries 3) Workarounds like background-size: 100% and SVG when native image solutions don't work

This document provides an overview of responsive web design. It defines responsive web design as an approach that aims to provide optimal viewing experiences across different devices.

The document discusses HTML5 APIs and new features available for video and canvas elements. It provides code examples for using the <video> element to embed video with controls and multiple sources, and for drawing shapes and images onto a <canvas> element using its 2D context.

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.

Although responsive designs are already state-of-the-art in web development the whole trend still is in its infancy. When it comes to images, a lot of responsive websites just load the same big image on every viewport. Because of this, people judge responsive design as being detrimental to performance. New markup elements like &lt;picture> are in development right now but what are the alternatives, what is the best to use right now, and how do they work? I will lead you through the different techniques and polyfills and show you their pros and cons. After this talk you should be able to choose the best fitting responsive image solution for your project.

In this talk I’ll look at how using Susy, a Sass grid framework, can make creating responsive grids for the web easier and speed up your design workflow. I’ll cover getting started with Sass and Susy in your Wordpress project, the advantages of using Susy, and some useful mixins and functions to help you create awesome grids.

Sass is a preprocessor scripting language that is compiled into CSS. It allows for nesting, variables, mixins, and other advanced features to help manage large CSS codebases. The document discusses how to install and use Sass via the command line as well as with GUI tools. Key Sass features covered include variables, nesting, parent selectors, combining selectors, imports, extends, and mixins.

Instead of relying on heavy, pre-formatted, markup-intensive CSS frameworks for grids, we can use a Sass grid framework to write clean, maintainable, performant CSS grid layouts. twitter.com/jdsteinbach jamessteinbach.com

This document discusses using Sass to implement responsive typography. It describes storing breakpoint widths, typography values like font sizes and line heights in Sass maps. These values are then looped through to generate responsive font sizes and line heights for different labels like headings, paragraphs etc. Functions are used to retrieve the font sizes and line heights from the maps based on the breakpoint and label. The values are then applied using CSS. This allows easy implementation of responsive typography in a maintainable way.

In this talk I look at how using Susy, a Sass grid framework, can make creating responsive grids for the web easier and speed up your design workflow. I cover the advantages of using Susy, how to get started and some of Susy’s mixins and functions, with visual demonstrations.

Is it too early to begin thinking about Google AMP outside of the Google news carousel? I’ll take you through the commons pitfalls of AMP and some of the results publishers are seeing.

Accelerated Mobile Pages (AMP) is a new web standard created by Google that aims to provide faster loading mobile web pages. Websites that comply with AMP standards and create separate AMP versions of their pages may see benefits like higher search rankings and increased conversion rates on mobile searches. However, AMP also tightly restricts the technologies used, requiring special iframes and prohibiting custom JavaScript. While AMP could sincerely aim to improve the mobile web experience, it may also be Google's attempt to respond to competitors and exert more control over web standards. Overall, supporting AMP is recommended given its current importance to mobile search.

This document introduces Accelerated Mobile Pages (AMP). It discusses how AMP addresses the problems of slow mobile page speeds and inconsistent user experiences by making pages load near-instantly. AMP uses HTML, CSS and JavaScript to simplify pages and optimize resources. The AMP cache hosted by Google further improves speeds by serving validated AMP pages from a global proxy. In summary, AMP aims to make mobile pages fast, easy to implement and embrace open web standards.

Der klassische Designprozess kommt im RWD-Zeitalter an die Grenzen. Der RWD-Workflow fordert eine iterative und inkrementelle Herangehensweise an Design und das daraus entstehende Frontend, das als Prototyp früh zu Verfügung stehen soll. Atomic Design ist ein sinnvoller und erprobter Ansatz, um dies zu realisieren. Der Vortrag geht dazu auf alle Aspekte von Atomic Design ausführlich ein und zeigt anhand eines Praxisbeispiels die konkrete Umsetzung.

Auf der Suche nach Innovationen werden viele Wege gegangen, von denen nicht alle wirklich zielgerichtet sind, sondern oft den Zufall als Freund haben. Design Thinking ist dabei ein vielversprechender und vor allem ganzheitlicher Ansatz, der das systematische Produzieren von Innovationen möglich macht und fördert. Und dabei steht noch nicht einmal zwingend eine Produktentwicklung im Vordergrund. Auch Managementprozesse lassen sich mit Design Thinking verbessern. Neben den theoretischen Grundlagen steht vor allem auch die Praxis im Vordergrund des kurzweiligen Vortrags.

Bootstrap è di sicuro diventato uno dei Framework front-end che tutti conoscono ed hanno utilizzato almeno una volta. Per alcuni Front-end developer è diventato uno standard de facto. Ma è davvero tutto oro quello che luccica? La sua velocità di utilizzo è in realtà assimilabile ad un prestito. Hai chiavi in mano, ma sai quanto andrai a pagare nel tempo? Durante questo talk vedremo quali sono le insidie che si nascondono dietro questo (e similari) framework e come sostituirlo grazie a tecnologie e metodologie moderne.

Have fast, performant, and successful web pages is a great Challenge. There are many layers involved and all of them have to work together. In this talk I presented at FIBAlumni with collaboration of COEINF and the video recording is at http://media.fib.upc.edu/fibtv/streamingmedia/view/22/1400 (in Catalan). It shows how all parts are involved in the success of web pages from the server up to the human brain and perception. It introduces metrics and ways to effectively calculate and measure objectively the impact of the actions taken in the optimisation and also some ways to detect ways to optimise websites.

From my presentation "I feel the need..the need for speed: Optimizing the User Experience", given at UXPA Boston 2014. This is the second half of the talk. The first half (are we slow? How slow? Why? And Why That's a Problem) used a ton of animation and rapid patter, and just doesn't make much sense on SlideShare without audio. I need to upload that to YouTube, someday.

This document summarizes strategies for optimizing a website's user experience by improving page load speeds. It discusses researching current page speeds and user locations/devices, setting performance goals, optimizing technologies like images, scripts and caching, improving information architecture to reduce page sizes, addressing trends that slow performance, and visual design techniques to decrease file sizes like using illustrations and CSS sprites. The overall message is that digital strategies must prioritize speed optimization to meaningfully improve the user experience.

Slides from Phil Nash's presentation at the London Web Meet-up - http://londonweb.org Speaker Phil Nash is a developer evangelist for Twilio and a Ruby and JavaScript developer. He loves test coverage, great beer, hackathons, and gems with puns in their names. Get all four together for maximum points. He once made a pull request to Rails... it's still open ;) Overview of session: Web application speed is paramount. Our users want our application and they want it now! We can optimise application code, database queries and so on, but that's all wasted if the page takes ages to appear. A fast back end and a slow front end can end up leaving a bad taste in the mouth. Using Rails, we'll look at the best ways to speed up the delivery of your application. Going beyond just minifying our assets, we'll look at techniques to get our site in the user's browser quicker, improving both real and perceived speed. We'll also discover the best tools to use to check out speed and get a better idea of the user's opinion of the site.Once finished, our sites will load in a flash!

This document discusses optimizing images for faster page loads. It recommends four simple optimizations: reducing image quality to 85%, using smaller file formats like WebP and SVG, sizing images appropriately through responsive images, and lazy loading images not initially visible. Implementing these optimizations can significantly reduce page weight and load times. The document provides examples and tools for each technique and data on their real-world impacts on mobile sites.

Using the browser width, screen resolution, and bandwidth to determine the appropriate image to serve through feature testing rather than browser sniffing. 2. Techniques for serving responsive images including using .htaccess files, the <picture> element, and JavaScript libraries like HiSRC that select images based on various tests. 3. Workarounds for older browsers including using background-size: 100%, SVG images, and font-based solutions.

Use a mixture of user agent detection and browser feature detection or a device detection library to enhance your responsive website.

Ein großer Bestandteil von Webseiten ist nach wie vor Text. Die weitreichende Unterstützung von Webfonts in modernen Browsern gibt uns die Möglichkeit, Schriftarten unserer Wahl für die Auszeichnung von Text zu nutzen. Allerdings gibt es auch Fallen bei der Verwendung von Webfonts, die gerade auf mobilen Geräten auftreten können. Lösungswege und Tipps für die Verwendung von Schrift im Responsive Webdesign. Zudem zeigt der Vortrag neue Möglichkeiten in CSS3.

Mittlerweile als moderne Technik etabliert, beschreiben zahlreiche Tutorials Umsetzungsvorschläge für Responsive Webdesign; dennoch stößt man in Projekten mit einem skalierbaren Layout auf immer gleiche Schwierigkeiten. Häufig haben mobile Geräte eine deutlich schwächere technische Ausstattung als der heimische Desktoprechner, sodass Fragen der Performance auf unterschiedlichen Devices in den Vordergrund gerückt werden. Gerade bei Bildern tauchen Begriffe wie "Responsive Images" oder "Adaptive Images" immer wieder auf. Welche Lösungen wann Sinn ergeben und wie man mit Retina-Screens umgeht, wie der aktuelle Stand des HTML5-Responsive-Image-Elements ist und wie man eine schlanke Bilder erstellt, werden in der Präsentation gezeigt.

Responsive Webdesign ist grad der heiße Scheiß, allerdings ist Responsive Webdesign mehr, als eine Desktopwebsite in eine mobile Ansicht zu quetschen. Es muss ein neuer Prozess her. Der alte Workflow "Auftrag bekommen > Recherche > Design erstellen > Abnahme > Design umsetzen" funktioniert so nicht mehr. Im Responsive-Webdesign-Prozess müssen alle Beteiligten eines Webprojekts von der ersten Sekunde an enger zusammenarbeiten. Zudem müssen frühzeitige und häufige Testphasen und Implementierungsstrategien gefunden werden.
