The Opera Web Standards Curriculum is a comprehensive online course that teaches you standards-based web design. This includes not only coding in the web’s foundational languages, HTML, CSS, Javascript, but also design theory.
One of the authors, Chris Heilmann, describes it as “probably the most thorough and up-to-date web standards curriculum on the web”. He writes:
During the whole course the main focus is on usability, accessibility and writing maintainable code. We deliberately left out browser hacks and backward facing solutions and build on the ideas of progressive enhancement and unobtrusive JavaScript.
I must also point out that WSC is part of Opera Education, an initiative that pushes for web standards awareness and enthusiasm for the internet industry, specifically in schools and universities. I think it’s important for these two parties—browser software makers and educational institutions—to work together rather than apart in developing the Web. In this regard, Molly Holzschlag believes the course is an A+:
The impressive aspect of the curriculum as it is now is that it’s comprehensive, including foundational topics such as Internet and Web history and evolution. Educators understand that history provides context for real learning. Sadly, this is an area often not available in books and online tutorials because readers typically want to dive right in and learn a given technique.
It’s difficult to find a course that focuses solely on creating things through the internet. It’s almost always integrated with either graphic design (see MTV Engine Room) or computer science. Because of this, there is no focus on employing the best practices in creating beautiful, functional websites. And it will continue to be that way—all the way into the workplace—without those two entities joining forces.
This is why I continue to admire Opera. (Mozilla does, too.) It pushes projects that are interesting and beneficial to the web community. Here’s another example: Opera Dragonfly. Firefox’s FireBug wasn’t created by Mozilla (although Safari’s Debugger is a native feature).
And unlike other browser vendors out there, Opera shows it cares about web standards not by saying but by doing.
You can never run out of things to talk about when it comes to cascading style sheets or CSS, but lately there have been developments that are more than worth your while. CSS3 is slowly but surely becoming mainstream thanks to several browser updates, while the gurus continue to think up smart ways to code those stylesheets.
Update: Ajaxian blogs that WebKit will support CSS variables. Amazing news that has come out just in time with this blog post. I’ve listed it below as well.
Tools and Frameworks
I’m not going to mention every imaginable CSS framework and piece of software out there, but these are worth looking at.
Stylizer: Skybound Software comes out with perhaps one of the most interesting (read: intuitive) CSS editors to date. It helps that it has a free version with a 14-day trial for its Ultimate counterpart.
YAML: Smashing Magazine shows how it is possible to create a flexible layout using Dirk Jesse’s HTML/CSS framework called YAML. The YAML Builder is an excellent plus.
CSS Cacheer: Shaun Inman releases a mini-application for CSS caching.
Best Practices
Here are some great nuggets of advice that will help guide you when writing your own CSS.
Font Stacks: The Unit Interactive blog lists various scenarios in which you should order your CSS font stacks. A PDF file is available for download, too.
Fun With Floating in the Grid: Devlounge recommends several practical CSS classes and layout techniques to achieve hassle-free floats and grids.
Performance Testing: jpsykes reports how the different browsers fare using different CSS selectors and attributes.
Faux Absolute Positioning: A List Apart comes up with a new layout technique that does away with hacks.
Nesting Specifics: DZone goes into the nuances of CSS selector specificity.
CSS3 and Beyond
If you’re still hesitant to use CSS3, you might change your mind now that some of the most popular browsers are slowly incorporating support for it.
Firefox 3: Killian Valkhof and David Baron write about support for several CSS3 features in the latest version of Mozilla Firefox. These include ligatures, kerning, font-size-adjust, inline-block/inline-table, and even text-shadow—coming in Firefox 3.1. The complete list is on Mozilla’s official page.
Opera 9.5: The Opera Developer Community discusses the CSS3 features its own browser supports, namely, @media, text-shadow, opacity, HSL values, overflow-x/overflow-y, :firstof-type, :nthchild, -o-background-size. Not to mention HTML 5 elements and SVG. Don’t forget to check out Opera’s debugging tool, Dragonfly.
Safari 3 has been out for a while now, but it’s Internet Explorer that we’re really waiting for. Unfortunately, IE8 will continue to lag behind.
Qualified Selectors: Shaun Inman proposes a different breed of CSS selectors.
CSS Variables: David Hyatt announces that WebKit now supports CSS variables as documented here.
