Detecting HTML5/CSS3 Features using Modernizr
HTML5, CSS3, and related technologies such as canvas and web sockets bring a lot of useful new features to the table that can take Web applications to the next level. These new technologies allow applications to be built using only HTML, CSS, and JavaScript allowing them to be viewed on a variety of form factors including tablets and phones. Although HTML5 features offer a lot of promise, it’s not realistic to develop applications using the latest technologies without worrying about supporting older browsers in the process. If history has taught us anything it’s that old browsers stick around for years and years which means developers have to deal with backward compatibility issues. This is especially true when deploying applications to the Internet that target the general public. This begs the question, “How do you move forward with HTML5 and CSS3 technologies while gracefully handling unsupported features in older browsers?” -

Rendering Text with the HTML5 Canvas
In a previous post I walked through the fundamentals of rendering shapes such as squares and circles using the HTML5 Canvas API. In this post I’ll provide a simple example of rendering and rotating text. To render text you can use the fillText() or strokeText() functions which take the text to render as well as the x and y coordinates of where to render it. To rotate text you can use the transform functions available with the HTML5 Canvas such as save(), rotate(), and restore(). To run the live demos that follow click the Result tab in the blue bar of each demo.

Getting Started with CSS Media Queries
If you've ever printed a page and noticed that it looks different than the actual page displayed in the browser you've more than likely witnessed a CSS media type in action. By using CSS media types such as "print", backgrounds, navigation bars, and other items can be hidden as a user prints which makes the printed page look much more readable. An example of changing styles through a CSS media type as a page is printed is shown next. This type of code can be placed directly in a <style> element in a given page or in an external style sheet.
