Web Developer Representation in W3C

Fronteers, the Dutch front-end association, is announcing their plans to become a member of the W3C, and to appoint Rachel Andrew as their representative. As a member, Fronteers will be entitled to four representatives, whom they intend to compensate for their time. Their mission is not without its challenges, however. Learn how you can help keep independent web developers' voices from slipping through the gutters.

Vexing Viewports

Each week, new devices appear with varying screen sizes, pixel densities, input types, and more. As developers and designers, we agree to use standards to mark up, style, and program what we create. Browser makers in turn agree to support those standards and set defaults appropriately, so we can hold up our end of the deal. This agreement has never been more important. That’s why it hurts when a device or browser maker does something that goes against our agreement—especially when they’re a very visible and trusted friend of the web like Apple. Peter-Paul Koch, Lyza Danger Gardner, Luke Wroblewski, and Stephanie Rieger explain why Apple’s newest tablet, the iPad Mini, creates a vexing situation for people who are trying to do the right thing and build flexible, multi-device experiences.

Smartphone Browser Landscape

Users expect websites to work on their mobile phones. In two to three years, mobile support will become standard for any site. Web developers must add mobile web development to their skill set or risk losing clients. How do you make websites mobile compatible? The simple answer is to test on all mobile devices and fix any problems you encounter. But with at least ten operating systems and fifteen browsers out there, it is impossible to do that. Nor can we test only in iPhone and Android and expect to serve our market. PPK surveys the mobile web market, as well as phone platforms and their browsers, and shows how to set up a mobile test bed that works.

JavaScript Triggers

Now that you’ve separated your website’s (XHTML) structure from its (CSS) presentation, wouldn’t it be great to similarly abstract the behavioral (JavaScript) layer from the others? ALA prodigal Peter-Paul Koch shows how to use JavaScript Triggers to do just that.

Rated XHTML

The W3C’s XHTML language is intended to bridge the web’s past (HTML) and future (XML). Shall we cross this bridge, now that we’ve come to it? Or is XHTML more trouble than it’s worth? Peter-Paul Koch puts forth the pros and cons.
