At MIX10 yesterday, Microsoft announced IE9 and spoke about its upcoming features. And, lo and behold, they released a Internet Explorer Platform Preview for anyone to download and play around with!
Drop shadow with CSS for all web browsers
One of the most common CSS effects is using shadows in various ways. Before, we needed to resort to images, but now we can offer this to all major web browser with CSS!
Geolocation in web browsers to find location & Google Maps examples
More and more services around us focus on where we physically are located at the moment, and how we can be assisted in the best fashion depending on that. Today I’d like to introduce the geolocation possibilities we developers have, and also play around a little with Google maps.
Do hidden elements load background images?
One thing I have always pondered about is whether elements that are hidden will load any images associated with it, either inline or through CSS, directly at page load. And apparently, my colleague Jonatan Larsson has as well.
Is WebKit too fast for its own good?
Let me start by saying I have the utmost respect for the WebKit team, and all the amazing things they have delivered with their rendering engine. Also, very important, for putting pressure on other rendering engine vendors and making them step up.
No more version of Mac OS X?
I recently read a, to say the least, interesting prediction about the future of Mac OS X.
The price of our hunt for better technology
We rush away in our lives, whining about slow computers and constantly have more and more demands. Maybe it’s time to take one step back and look at the consequences of our desires.

Time for another Geek Meet, and this time, we’l be trying something new. 
CSS display: inline-block: why it rocks, and why it sucks
Usually when you want a horizontal list, you need to use float in the CSS code to make it work, with all its drawbacks. However, there is an alternative with display: inline-block.
CSS files downloaded twice in Internet Explorer with protocol relative URLs
I think we can all agree that performance of web sites matters a lot, and slow web sites are very annoying both for developers and, more importantly, end users. Therefore, we need to talk about a newly discovered problem: Internet Explorer, protocols and inclusion of stylesheets.
CSS gradients for all web browsers, without using images
One thing that is quite nice is that we now have the ability to create gradients in our pages just from CSS code, and without the use of any images.

The video element in HTML5 – great possibilities, but also codec and licensing problems
Man has always been inspired by things moving around and giving away noises, so it was just a matter of time before video content showed up on the web. For a number of years, Flash was the de-facto standard of showing video, but now, with HTML5, the video element has made its way into our lives.
IE and Life
The other day I sort of had an epiphany, a revelation if you will, which made me realize something hard to accept: Internet Explorer will always be there throughout my entire career working with Internet.

CSS background transparency without affecting child elements, through RGBa and filters
Looking at the design of most web pages today, almost exclusively all of them include some semi-transparency of elements. However, getting the desired effect in CSS is harder than one might think.

Releasing Inline Code Finder as a Google Chrome extension
I put a lot of time into ensuring web interface code quality, both for code in projects I work in and in doing code audits for other web sites. One of the best ways to find undesired inline styles, inline JavaScript events and javascript: links, I believe, is my Inline Code Finder extension and now it’s available for Google Chrome as well!
Testing Object-Oriented CSS (OOCSS) for easier CSS development
Let’s face it: developing CSS that should work across various web browsers and platforms is hard, and could prove to be quite a challenge. This is where Object-Oriented CSS (OOCSS) steps in.
Content Management Systems are a dying breed
Based on my experience and thoughts over the years, and feedback from a number of very smart and talented people, I believe that Content Management Systems (CMS) are far from the promised savior, but rather the bane of web sites.
