Many of the emerging techniques in CSS3 are particularly well suited to interactive Web page elements such as buttons. In this tutorial we will explore using CSS3 properties including transforms, transitions, box shadows, backgrounds and rounded corners. We will be working with an anchor element, animating the button when it is in hover state. Most modern browsers support the bulk of the properties we will be using, but users with non-supporting browsers will still be able to see and interact with...
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...
Have you ever come across a beautifully designed website and wished you had X-ray vision to see how all those HTML elements on the site work? Have you ever wanted to see how a certain design might look on your site without actually changing the underlying code? Well, you don’t have to wish or think anymore because a powerful and really useful browser extension called Firebug can help you do all that. Any designer or developer looking to experiment with different styles on a website in real-time needs...
HTML5 includes a host of new input elements, such as the output tag. Using the output tag in conjunction with the "oninput" event listener, you can create simple or complex Web page calculators, giving the user instant results. The output tag allows you to build forms using semantic markup, since the element is specifically designed for displaying calculation results. In this tutorial we will create a simple Web page calculator to demonstrate using the output element. Many of the new input elements...
With HTML5, you can set any of your Web page text elements to be editable by users. Using the "contenteditable" attribute, you can instruct the browser to allow users to insert, delete and alter the text your page contains as they view it. There are many possible uses for this technique, such as allowing users to customize the way your pages appear to them each time they visit. In this tutorial, we will run through the basics of letting users edit your text content, including saving their edits for future...
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...
With CSS3, you can rotate Web page elements by a specified number of degrees, clockwise or anti-clockwise. With a small amount of HTML and JavaScript code in conjunction with CSS declarations, you can also animate these rotations. In this tutorial we will work through the process of rotating an image element by varying amounts as well as animating the function, initiating the rotation on user interaction with the page. Create a Page ... Save a new HTML file in your chosen editor, using the following...
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...
