Your First Multi-Device Site   Creating multi-device experiences is not as hard as it might seem. In this guide, we will build a product landing page for the CS256 Mobile Web Development course that works well across different device types. Building for multiple devices with differing capabilities, vastly different screen sizes and interaction methods can seem daunting, if not impossible to get started. It is not as hard to build fully responsive sites as you think, and to show you, this guide takes you through the steps that you can use to get started. We have broken it into two simple steps: Defining the information architecture (commonly known as IA) and structure of the page,Adding design elements to make it responsive and look good across all devices.

Box-shadow, one of CSS3′s best new features Home / CSS3 Previews / Box-shadow, one of CSS3’s best new features The box-shadow property allows designers to easily implement multiple drop shadows (outer or inner) on box elements, specifying values for color, size, blur and offset. Browser support is growing of late with Mozilla (Firefox), Webkit (Safari/Chrome/Konqueror), Opera and the IE9 Platform Preview all offering a decent implementation of the spec, although Mozilla and Webkit still require their respective -moz- and -webkit- prefixes (note Mozilla Firefox 4.0+ no longer requires the -moz- prefix).

Forward Thinking Form Validation Form validation has been a finicky business since the web was born. First came the server-side validation error summary. Then we evolved to client-side validation to verify results inline. Now, we have the marching giant that is HTML5 and CSS3: HTML5’s forms chapter offers new input types and attributes that make validation constraints possible. CSS3’s basic UI module provides several pseudo-classes to help us style those validation states and change a field’s appearance based on the user’s actions.

10 Fun Browser Games For Learning Web Development Danny Markov Playing video games often involves solving tricky problems with logical thinking and trial-and-error strategies. Can you think of something else that requires these skills? cvsGraphCtx Manuel de référence Cango3D Canvas Graphics Object 3D, Cango3D, is a graphics library for the HTML5 canvas element. Cango3D uses the fact that straight lines and Bézier curves maintain their shape under 3D transformation. Restricting object outline definitions to these types means that smooth curves can be drawn in 3D with very few points needing to be transformed and projected onto the 2D canvas. The current version of Cango3D is 4.06, and the source code is available at Cango3D-4v06.js.

Constraint Validation: Native Client Side Validation for Web Forms Introduction Validating forms has notoriously been a painful development experience. Implementing client side validation in a user friendly, developer friendly, and accessible way is hard. Before HTML5 there was no means of implementing validation natively; therefore, developers have resorted to a variety of JavaScript based solutions. To help ease the burden on developers, HTML5 introduced a concept known as constraint validation - a native means of implementing client side validation on web forms. Yet, despite being available in the latest version of all major browsers, constraint validation is a topic largely relegated to presentations and demos.

JavaScript animation Object movement JavaScript makes webpage content dynamic, allowing user interaction and animation. The principle of JavaScript animation is rather simple; webpage elements, most often images, have their style or position within the page altered by a script. Repeating this process at sufficiently short intervals has the effect of simulating smooth motion of the element about the page. Card Flip · Intro to CSS 3D transforms › Docs We now have all the tools to start making 3D objects. Let’s get started with the basics, flipping a card. Here’s the basic markup we’ll need: <section class="container"><div id="card"><figure class="front">1</figure><figure class="back">2</figure></div></section> The .container will house the 3D space.
