I haven’t posted about this yet. I’m an incredible idiot. I’m presenting at the Boston PHP group in October. My presentation is a couple of weeks before Steve Krug. No pressure.
Is CSS still a mystery to you? Do you find yourself editing your styles over and over justo get them to display correctly in IE and Firefox? Have you created a powerful application, and want it to look nice and clean? Do you want to take your knowledge of CSS and Design to the next level?
In this presentation Rob Larsen will step through the basics of Cascading Style Sheets (CSS,) the visual language of the Web. Starting with the most fundamental concepts and finishing with concrete examples illustrating common patterns, this presentation will serve as a launching point for those new to CSS and will strengthen the understanding of the core principles for developer or designer more experienced with CSS.
In this event you will learn:
Basics of CSS
Design & Layout
Web Standards
Rich Visual Behaviors
CSS1, CSS2, CSS3
Frameworks, Abstractions, etc.
Dealing with cross browser support
Separation of style, content and behavior
Testing
Tips & Tricks
If you still fumble with CSS and want to take your experience to the next level, then this event is for you.

In case you missed it the latest Internet Explorer 9 Platform Preview is out and it’s a thing of beauty. It added Canvas support so the first thing I did was run it through some demo code. It’s faster than Chrome. Visibly faster. No benchmarks needed. It’s such an incredible difference from the current Internet Explorer family which are many times slower than the good browsers out there.
The good news doesn’t stop there. There’s actual standards support.
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.
Here are the numbers for DrunkenFist.com in the year 2009. There were 614,333 visits to that domain last year and the top browsers broke down like this:
Yes, I’m still helping out with screening candidates. I haven’t yet interviewed someone to replace me, but there’s still a week to go.
Anyway, we’ve had a couple of technical questions that candidates universally failed to answer. Why share them here? For starters I just want to know if we’re crazy to expect people to know these. I also like the idea of a kind of “easter egg” for candidates. If someone does enough research to find my blog and read this post, they’ve shown me something, even if it’s not the answer to one of the questions posed below.
The two that have surprisingly turned into stumpers (at least for the last five or six folks I’ve interviewed)
What is hasLayout?
What’s the significance of setting the body text to .625em?
And the bonus question that I want to ask, but don’t, because it’s kind of goofy to say out loud
Simple. It serves a new style sheet to various versions of IE as needed. The bad thing is the extra HTTP request added onto the Microsoft browsers. I’m not even there yet, but during one of my interviews for the new gig an alternative was suggested- using conditional comments to append a different class to the html element and letting the cascade sort it out.
Once again rounding up some of the articles I’ve read over the past couple of weeks.
All style tags after the first 30 style tags on an HTML page are not applied in Internet Explorer
I wasn’t surprised to see this came up as an issue in the Drupal community. During my short time working with Drupal, I was horrified by the number of style sheets/JavaScript files included in the page. I don’t think we ever got to 30, but 10-15 was scary enough. Apparently, there’s a “performance” mode which clears that up, but I never made it that far…
While some of the functionality of MS’s CSS filters is actually pretty useful (sue me, I need to use them from time to time), the implementation is ugly as hell. Ryan, one of the smart guys here that helps me fool people into thinking I know what I’m doing, had to implement the Microsoft gradient filter as a (brilliant) hack for a performance issue on a small subset of IE browsers. We were discussing the solution and then he called up the code. Read the rest of this entry »
Once thing that’s vital to testing the accessibility of a web app or site is running through it without using a mouse. If you can successfully work a site or app without touching the mouse, you’ve gone a long way towards ensuring that your site is available to a wide range of people and devices.
One thing that’s difficult about that process is most of us rely far too much on the mouse when browsing. Which is where these lists of keyboard shortcuts for Firefox, and Internet Explorer come in handy. Read the rest of this entry »
Conditional Compilation is a handy, Internet Explorer specific method for forking bits of JavaScript. The nice thing about it is that real browsers don’t notice it at all. It just looks like a comment block to any non-IE browser. Which saves the rest of the world from even having to if (IE) { } else { } . I like that.
Anyway, we use it to fix some of IE’s shortcomings. One standard pattern is using it to fake the :hover pseudo-class on inputs in IE6. Something like this:
//IE6 HOVERS simplified//
//this would be a bit different in protection
//but you can see the idea
/*@cc_on @*/
/*@if (@_win32)
var inputElements = document.getElementsByTagName("input");
var test = inputElements.length;
for (var i=0; i<test; i++) {
if (inputElements[i].getAttribute("type") == "submit"){
inputElements[i].onmouseover = inputElements[i].onfocus = function(){
addClass(this, "hover");
}
inputElements[i].onmouseout = inputElements[i].onblur = function(){
removeClass(this, "hover");
}
};
};
/*@end @*/
//END IE6 HOVERS//
