“Pragmatic Guide to Sass” is in Beta!

by Joey deVilla on August 24, 2011

Sass

Sass, which is said to be short for “Syntactically Awesome Stylesheets”, is a meta-language that extends CSS3 to do things that plain old CSS can’t do easily or at all, with goodies we’ve come to know and love from our programming languages: variables, nesting, mixins and inheritance. It compiles to well-formatted standard CSS, and you can even have Sass watch your Sass files so that it automatically updates your compiled CSS files as you update your Sass source.

Haml

Sass is the creation of Hampton Catlin, a “Shopifriend” and programmer who’s all about optimizing his programming tools. When he got fed up with building HTML templates for his Rails projects, he created the Haml markup language. Haml’s popular enough that it’s found its way into the most unlikely of places, such as the .NET world, where they’ve implemented it as NHaml. Just as Haml is Hampton’s optimization of HTML, Sass is his optimization of CSS.

Pragmatic guide to sass

It’s only fitting that Hampton is the co-author of the upcoming Pragmatic Bookshelf book Pragmatic Guide to Sass. Like Hampton, it gets straight to the point; it’s going to be about 100 pages long. He recently tweeted that “doing more than 100 pages just seemed like filler.” Given that I’m already behind in my tech reading, I’m glad that Hampton (and his co-author Michael) insist on keeping things concise.

Pragmatic Guide to Sass is currently in beta. You can get it in ebook format immediately (with downloadable updates as more of the book is finished, including the final, finished ebook) for US$13 or buy the ebook + paper book bundle, where you can get the ebook now and both the paperback edition and the final, finished ebook when the book is complete for US$30.

IE’s Big Leap Forward

by Joey deVilla on June 28, 2010

"nine" spelled using the IE logo for the "e"Peter-Paul “ppk” Koch writes in his blog, QuirksBlog (which lives on his site, QuirksMode):

In the past few days I’ve been revising the CSS compatibility table with information about the latest crop of browsers. There’s no doubt about it: this is IE9’s show. It just supports nearly everything. No hassle, no buts.

Microsoft has finally taken the big leap forward we’ve been waiting for ever since they announced their decision to restart IE development back in 2005.

IE9 promises to be an excellent browser. Its CSS support is now at par with that of the other browsers — although each browser still has its specific areas where it performs less. But we cannot in good faith say that IE is behind the others any more.

In the article, he does a run-down of CSS selectors and finds that the upcoming IE9 does an excellent job of supporting them.

Go take IE9 for a spin – download Platform Preview 3 and try it out – and make sure to try your hand at CSS 3 as well!

IE9 Platform Preview 2

by Joey deVilla on May 6, 2010

It wasn’t that long ago that an early version of Internet Explorer 9 – we called it Platform Preview 1 – was announced at MIX10 Conference back in mid-March. If you missed it, here’s MIX10’s Day 2 keynote session, in which the Internet Explorer team’s supreme Kahuna, Dean Hachamovitch, made the announcement (it’s the first part of the keynote, so you don’t have to watch or scan through the entire two hours):

or watch the video in WMV, high-def WMV or MP4 format.

As I wrote back then, IE9 showed a lot of improvements. In addition to the improvements, IE9 came with a commitment made to updating the preview about every eight weeks.

The time has come to announce the release of IE9 Platform Preview 2! The whole story’s over at the latest post to IEBlog, but I thought I’d cover a couple of things I felt were worth noting.

Improved JavaScript Performance

Chart showing JavaScript performance of various browsers

The chart above shows the results of various browsers, including IE9 Platform Preview 2, under WebKit’s Sunspider JavaScript benchmark, version 0.9.1 on a 3.0GHz Dell Optiplex with an Intel Core 2 Duo processor, 4GB RAM and Intel Integrated Video running Windows 7. As you can see, JavaScript performance on Platform Preview 2 is a mere eye-blink away from that of the Esteemed Competition.

If you’d like to run the SunSpider JavaScript benchmark in your default browser right now, click here.

Getting HTML5ier

Acid3 test for Internet Explorer 9 Platform Preview 2 - 68/100

The goal for the final release of IE9 is full HTML5 compliance and “Same Markup” – that is, rendering the same HTML, CSS and JavaScript the same way. The idea is that you, the web developer, shouldn’t have to come up with workaround or hacks to get the same page to display the same way across browsers.

If you’d like to run the Acid3 test in your default browser right now, click here.

Part of that approach is technical: a standards-compliant IE9, and the first platform preview was a step in that direction. Platform Preview 2 add more fixes to HTML, SVG, CSS3 and JavaScript implementations as well as features like CSS3 media queries, DOMContentLoaded, DOM traversal and range, getElementsByClassName, createDOcument and so on.

While the Acid3 test isn’t the holy grail – some of its tests don’t mesh with the HTML5 standard as it is right now, others are still “under construction” – more compliance with HTML5 typically means a higher Acid3 score. IE9 Platform Preview 2 currently scores 68 out of a possible 100, which is an improvement over Platform Preview 1’s score of 55, and leaps and bounds ahead of IE8’s scores for 20.

People Issue #1: Standards

Another part of the “Same Markup” approach is working within the various standards groups defining the web experience. Among other things, we’ve been doing things like:

People Issue #2: Developers

Let me show you a couple of photos from Toronto Code Camp, which took place last Saturday. Here’s Colin Bowern’s session, titled JQuery is Your Friend:

Colin Bowern presenting at Toronto Code Camp to a packed room

That was a fairly packed room, but that ain’t nuthin’ compared to Todd Anglin’s afternoon session, The Rich Standard: Getting Familiar with HTML5, which went beyond “standing room only” and into the “any place I can park myself” zone:

From looking at the crowd – and yes, talking with them, too – it’s quite clear that there’s a lot of hunger for information, tutorials, guidance and general knowledge of HTML5, CSS3 and JavaScript and how to build modern web applications using them.

That’s where I can help, and in all sorts of ways. For starters, there will be a number of HTML5, CSS3 and JavaScript articles, tutorials and pointers on this blog. I’ll also be participating in a number of presentations, workshops and TechDays events to cover HTML5, CSS3 and JavaScript. Keep watching this space for more.

Take IE9 Platform Preview 2 for a Spin!

Windows Internet Explorer 9

You can download Internet Explorer 9 Platform Preview 2 right now. As with Platform Preview 1, it coexists with Internet Explorer 8, and it’s a very thin wrapper around the engine, meaning that it’s really for developer and designer testing rather than general browsing. The UI elements you’d expect in a browser, such as the address bar (you open sites using File –> Open…), nor are the security features such as Protected Mode, SmartScreen filter and XSS scripting filter.

Platform Preview 2 installs right over Platform Preview 1; you don’t have to uninstall Platform Preview 1 before installing Platform Preview 2.

Take it for a spin and send us feedback!
