I’ve read a number of articles about the best approach for delivering content to mobile devices using CSS3 Media Queries, including Ethan’s article at A List Apart. While the general consensus seems to be “be careful”, I decided to do some testing of my own. Of course this “be careful” attitude is because, done incorrectly, you can cause a mobile device to download much more than you think. Oh, and there’s also the problem of that pesky Internet Explorer thingy… The question that I wanted answered is simply “what does a mobile device download when encountering a page using media queries?”

First, I created a simple page that contains a few boxes (list elements styled with CSS). In addition to text, one of the boxes contains (more…)

While I truly am excited by the new semantic elements in HTML5, as well as the possibilities that things like local storage will do for expanding the capabilities of websites, I have to admit that I’m really much more excited by the shiny new toys in CSS3. And, of course, with the recently released HTML5 pack for Dreamweaver CS5, I no longer have to “try” to remember the new CSS3 properties – I get them all with lovely code-hinting and code-completion right within Dreamweaver CS5.

In the following video, I show you how to use some of the really popular new properties – like using border-radius to add rounded corners, transform to rotate elements and transitions to create the illusion of an animated rollover.

There is a definite caveat that I want to make sure to mention – since CSS3 (and HTML5, of course) is still being developed, not all of the CSS3 properties are available in Dreamweaver CS5 (and in Live View some properties do not render). But even with that caveat, Dreamweaver CS5 now really rocks with CSS3. And again, if you’ve not looked at Dreamweaver lately, you can always download a 30-day trial.

Unless you’ve been living under a rock, you know the underlying language of the web, HTML, has begun to (finally) evolve once again with the browsers slowly beginning to support pieces of HTML5 and CSS3. With the release of Dreamweaver CS5, the world’s leading web authoring tool has made huge strides in embracing the evolution of the web, providing an unparalleled ability to style themes for any PHP-based CMS system (WordPress, Drupal and Joomla out of the box, as well as home-grown PHP-based systems). However, for those who have already upgraded and who want to leverage HTML5 and CSS3, you’ve no doubt found that the only “apparent” support for HTML5 in Dreamweaver CS5 is the addition of the HTML5 doctype in the New Document dialog. But now, that’s all changed!

During the keynote session at the Google I/O Conference in San Francisco, Adobe’s CTO, Kevin Lynch, demonstrated an extension to Dreamweaver CS5 which not only adds the new HTML5 semantic elements, but also properties for CSS3, to the authoring environment. With this addition, Dreamweaver CS5 users are provided with code hinting for HTML5 and CSS3 in Code View.

Of course, HTML5 and CSS3 are not “finished” yet, and as such, the team can’t “know” what’s going to be in the final specification. Therefore, the extension provides support for the elements and properties that are “the most complete” at this time. In other words, the elements and properties that, (more…)
