With the continued adoption of advanced CSS by browsers, we are starting to have the ability to do more and more using just CSS. As we have seen, you can make all kinds of crazy shapes with only CSS. On a recent client project, Trevor Davis has created a grid of diamonds with CSS and shared the tutorial: Who Says the Web is Just for Squares?
He is using Modernizr to detect if the browser supports CSS3 Transforms. And, he is using Sass and Compass for all of the CSS. You may now go forth and make some creative layout with different shapes.
Requirements: Sass and Compass CSS

Modern browsers like Internet Explorer 10 are implementing stable versions of some interesting HTML5 features, including the offline, drag and drop and file APIs. These features are bringing us a new era of Web applications and fresh, quickly emerging gaming scenarios. In this two-part article, I’ll show how I used these new features to modernize my last HTML5 game, HTML5 Platformer. In this article, I’ll cover hardware scaling and CSS. In Part 2, I’ll cover the offline, file and drag-and-drop APIs. I hope you’ll get some great new ideas for your own games!
Note The URL demo is at the end of this article. Feel free to play using your favorite browser, and check out the Internet Explorer 10 gameplay video. The source code will be available for download in Part 2.
Scaling Across Devices
If you’re building an HTML5 game, you’re probably interested in the cross-platform nature of this standard programming language. But compatibility with a broad variety of devices means you have to take into account a huge number of resolutions. Compared to SVG, Canvas—at first—seems ill-prepared to handle this.
However, with a casual game based on sprites, there is a simple solution to implement. David Catuhe has done a great job of describing this on his blog, Unleash the power of HTML 5 Canvas for gaming – Part 1 (see the section called “Using the Hardware Scaling Feature” for specifics).
The idea is as simple as it is smart. You’re working inside a canvas at a fixed, predictable resolution, and you’re stretching it to the current displayed resolution using the canvas.style properties. Read the rest of this entry »
Defining and deriving types with WinJS.Class
In the sections below, we’ll talk about how you can use the define and derive methods in the WinJS library to quickly create your own custom types, and specify their property constructors.
The properties that are added to the prototype of an object appear on any object that is instantiated by calling its constructor function, but the properties added to the type directly belong only to the type itself.
For example, let’s say we want to define a class Robot, which has an instance property name and a static property harmsHumans. The modelName property belongs to the individual objects created with Robot(name) contstructor function, but the harmsHuman property is valid for all Robot objects. Read the rest of this entry »
Web standards like HTML5 and CSS3 continue to change. One of the most significant changes has been the W3C Candidate Recommendation for CSS Gradients which allows developers to code for modern browsers like Internet Explorer 10 without using vendor prefixes. In this article, I’ll take you through some differences between the old and new syntax and behavior and provides some insight into the change. Hopefully it will save you some time as you support many browsers.
Note: IE10 stills supports older CSS Gradients syntax from the W3C Working Draft of 17 February 2011 behind the vendor prefix -ms- so your current code won’t break.
Should you choose to simplify your CSS by making the move from vendor-prefixed CSS3 Gradients to unprefixed CSS3 Gradients, there are some key syntax changes to be aware of. Many gradient generators have provided cross-browser markup, including markup for unprefixed gradients. In many cases, the unprefixed markup is no longer valid according to the CSS Image Values W3C Candidate Recommendation that covers gradients. Here are the changes you should be aware of.

This article is the second part to: How to Create a Windows 8 RSS Reader App with HTML5. If you haven’t read it, check it out first.
We’re now going to see how to display the details of each article. We will use for that a transition animation, we will play with the simulator and we will continue to discover Blend to use CSS3 Multi-columns for instance.
Like in the previous article, you’ll find the source code to download at the end of the article.
During this article, we’ll see:
- Step 1: using the simulator
- Step 2: displaying the articles’ details
- Step 3: finishing the design of the detail view with Blend
- Step 4: source code to download and conclusion
Note: this article has been updated on 21/08/2012 to implement the changes in the UI & in the code between Windows 8 Release Preview and RTM. In a general manner, if you need to migrate your application from RP, you should read this document: breaking changes document. In our case, there was 0 impact between RP & RTM here.

One way to do this is to have a function execute at a later time, as with event handlers, which are invoked after another call has raised an event. Callback functions are another kind of asynchronous processing, because they call back into the code that initiated the process. Read the rest of this entry »
These effects can be accomplished by transforming the HTML <body> element using CSS Animations. However, this use case presents some considerations that we felt were worthy of discussion, such as the effect of layout and sizing on transforming <body>, as well as how to appropriately time page navigations so that they mesh properly with our animations.
The code samples in this post use unprefixed CSS markup as supported by IE10 Release Preview; other browsers may require vendor prefixes for the CSS Animations and CSS Transforms properties used. Read the rest of this entry »
This first article will help you to create the welcome screen that will use a WinJS ListView control. This control will display all the blog posts recently published via nice thumbnails. The 2nd one will work on the detail view displayed when you’ll click on one of the items. At last, you’ll find at the end the final solution to download. See it as useful complementary resources if you need to clarify some parts of this article. Read the rest of this entry »
Modern browsers like Internet Explorer 10 and 9 introduced sub-pixel font positioning as part of its hardware-accelerated rendering of HTML5 content. That was an important step into the future as it enabled zoom-independent text metrics—an important characteristic when touch gestures like pinch-zoom are part of the browsing experience on Windows 8 touch-enabled devices. This article shows how easy it is to help your fonts look better across many browsers by declaring Standards Mode.
Zoom Example: Legacy vs. Standards Modes
Below are side-by-side comparisons showing text from a popular news site in 8 and 10 document modes at 100% and 150%. Note the especially poor letter spacing between some letters in the 150% 8 mode example (upper right).
