Responsive Web Design 帶來了網頁技術的革新,僅僅透過 Media Queries 偵測螢幕尺寸,便能提供適合不同尺寸裝置的內容與樣式。
但光是從螢幕尺寸來偵測行動裝置的瀏覽能力,無疑是瞎子摸象。近兩年內的智慧型手機已經數度提高尺寸與解析度,行動網頁的媒體品質與豐富性也須一併提升。在內容品質提升的同時,過多的圖片或物件可能會降低使用者經驗或付出較高的代價。
從技術角度來看,可歸納『資源一致性』、『相容彈性』、『環境適應』、『品質最佳化』等四個要素。本題將就此四項要素介紹應用實例,說明如何提高 Responsive Web 的彈性,並增加行動網頁瀏覽效率。
Node.js is a framework for building scalable server-side applications and network programs using asynchronous JavaScript. It has a non-blocking I/O model that uses a single-threaded event loop which improves speed and reduces memory usage. Key benefits include its fast performance, non-blocking I/O, small memory footprint, use of the V8 JavaScript engine, and ability to be used for both frontend and backend development through its reactive programming approach.
React is a JavaScript library for building user interfaces that was created by Facebook. It renders user interfaces and responds to user interactions by reducing complexity and improving performance behind the scenes. React uses a virtual DOM diff implementation to render on the server or client with high performance, and optional JSX syntax sugar makes the code easier for engineers and designers to work with. Major companies like Facebook, Netflix, and Airbnb use React for its portability, performance, maintainability, comprehensibility, and testability.
Java Serverless Application Development using Microsoft Azure - DevJam 2021shaunthomas999
?
The document discusses developing Java serverless applications using Microsoft Azure. It introduces serverless and microservices concepts and provides an overview of developing Azure Functions using Java. It includes links to documentation, tools, and a demo application repository for building serverless functions with Java on Azure. The presentation aims to help understand serverless development options and provide resources for creating Java serverless applications on Azure.
React is an open source library for building user interfaces and mobile apps. React Native allows developers to use React to write and deploy native mobile apps for iOS and Android from the same code base. It uses a virtual DOM for rendering to provide high performance while allowing cross-platform development with shared code for both platforms.
The document discusses running Node.js applications on Windows Azure. It begins with an introduction to Node.js and demos of building a simple Node.js app. It then discusses how LinkedIn uses Node.js extensively for their mobile backend. Finally, it covers deploying Node.js apps to Windows Azure Websites, including support for Node.js, tools like NPM, and databases like MongoDB on Azure.
George is a JavaScript engineer with over 10 years of experience building scalable and maintainable web applications using technologies like Node.js, Express, MongoDB, AngularJS, ReactJS, and Ember. He enjoys taking on challenges and pushing technical boundaries. Some of his past roles include working as a senior full stack developer at PaySafe implementing Ember applications, and as a full stack JavaScript developer at Global Radio helping establish a new AngularJS, NodeJS, and Docker stack.
This document discusses developing, deploying, and maintaining a ReactJS UI for the mobile web from a large news portal. Some key points include starting with the views, using stateless components, and that it's okay to use jQuery. Lessons learned are that applications have UIs, websites have pages, and modules can be used instead of frameworks. The future of UI development is seen as platform-independent components, and mobile web is still relevant.

The document discusses principles of responsive and adaptive web design. It covers topics like flexible layouts, images and media, media queries, breakpoints, grids, and frameworks like Bootstrap. Flexible layouts using percentages allow content to scale and reorganize across devices. Images and media should resize proportionally. Media queries apply different CSS styles based on screen width conditions. The grid helps layout content consistently. Frameworks like Bootstrap provide tools to build responsive sites more easily. The goal is to design sites that adapt to various contexts like device type or width.
This document discusses browser engines and summarizes key points:
1. It describes how browsers work at a high level, including parsing HTML and CSS to build DOM and render trees, performing layout and painting, and using JavaScript engines.
2. It covers advanced rendering technologies like hardware acceleration, compositing, and threaded rendering to improve performance.
3. It provides tips for engine developers to optimize layout, painting, and rendering, such as using layers and translation instead of positioning to reduce reflows.

responsivedesign.ca was launched in February of 2012, and it was well received. It was our first mobile-first responsive site. We built it quickly and knew it wasn’t perfect, but the game plan was to launch early and incrementally improve the site over time.
It’s not even a year later we use whole new workflows, creative design methods, modules, and development tools in our responsive websites. This talk will highlight how we created the original project and what we’ve since learned regarding workflow and development including:

Da tela retina ao Google Glass, design responsivo n?o é feature é obriga??o.Pedro Marques
?
This document discusses responsive design and designing for different screen sizes and devices. It covers topics like retina/high resolution screens, device pixel ratios for mobile devices, and considerations for new platforms like Google Glass. It emphasizes that responsive design is not just for mobile, but creating flexible experiences across all devices. Key quotes encourage delivering content to users however they want to consume it and that it is the designer's responsibility to provide a good experience across formats.
Advancio, Inc. Academy: Responsive Web DesignAdvancio
?
Responsive web design allows a website to adapt to different screen sizes using fluid grids, scalable images, and media queries. It involves developing sites using relative units like percentages instead of pixels so elements resize proportionately. Media queries allow different CSS stylesheets to be loaded depending on screen width, orientiation, resolution and other factors. This allows a single website to be accessed seamlessly on any device from phones to desktops to tablets without needing separate mobile sites.
Responsive Web design is the approach that suggests
that design and development should respond to the
user’s behavior and environment based on screen size,
platform and orientation. The practice consists of a mix
of flexible grids and layouts, images and an intelligent
use of CSS media queries. As the user switches from
their laptop to iPad, the website should automatically
switch to accommodate for resolution, image size and
scripting abilities. In other words, the website should
have the technology to automatically respond to the
user’s preferences. This would eliminate the need for a
different design and development phase for each new
gadget on the market.
