The official January 2011 launch of the robust HTML5 has brought with it a number of powerful coding elements. Among them is the <progress> tag, a very useful tool in putting together quick, attractive online presentations. CSS3 provides a highly flexible methodology for customizing default HTML5 tags. At present, both technologies are undergoing considerable revision. ‘Pseudo-elements’, such as those prefixed by -moz- and -webkit-, were implemented within the CSS3 framework...
HTML5’s native audio element will be a great way to avoid having to rely on third party plug-ins like QuickTime and Flash. The latest web browsers like Chrome 10+ and Firefox 3.6+ are already there with imbedded javascript libraries which provide methods and properties for manipulating the <audio> element. In this post, we’ll examine a few of the most important methods and discover ways to use Javascript to run audio files. NOTE: Although this post focuses on the Audio object, these methods...
In the past, the W3C debated whether page transitions belong in our CSS stylesheets, under the domain of web designers, or in our code, under the domain of web developers. After much lobbying by both designers and developers, they created a working draft for transitions. Once this specification is officially adopted, CSS3 Transitions will become a standard tool in web browsers. Until that time, we had to rely on vendor prefixes for this feature. NOTE: IE9 does not support the CSS3 Transitions...
With CSS3, you can apply animated effects on Web page elements in 3D as well as 2D. In this tutorial we will go through the basics of rotating in 3 dimensions and will combine these transforms with the scale and translate transforms for more complex results. We will also add a basic level of interaction to animate the effects as the user interacts with the page. Create a Page with an Image Element ... Create a basic page with a CSS section in the head area, as follows: <!DOCTYPE html> <html> <head>...
Savvy web developers often use vendor prefixes to try out the latest browser styles before the styles have been approved by the W3C and turned into a standard. By specifying a browser or vendor prefix within your CSS stylesheet or style property within a JavaScript function, you can gain control of how an element will render within a specific browser (Chrome, Firefox, IE, etc.). This gets you access to these browser’s newest and coolest styles and elements. This article will illustrate how to...
CSS3 transforms allow you to apply various visual effects to the items in your Web pages, including scaling elements to either increase or decrease their size. The scale transform requires only a single CSS declaration, but to ensure your pages work in the different CSS3 supporting browsers, you do need to add amended versions of the declaration to your code. As with any transform, you can apply the CSS3 scale effect on user interaction, as well as using an animated transition. Create a Page ... Create...
CSS3 offers a wealth of possibilities in terms of visual and interactive effects, even allowing you to create animated elements without the need for either Flash or JavaScript. In this tutorial we'll go through the process of translating a page element using a CSS3 transform. The translate function essentially moves an element by a specified distance along the X and Y axes. You do need to provide browser-specific code to create reliable transforms, but the technique is not particularly complex....
