Adding HTML5 placeholder attribute support through progressive enhancement
I continually talk about HTML5 and how progressive enhancement is a simple approach to make any new behavior possible in web browsers that haven’t implemented it yet. I thought I’d show you a simple example how to do this with the new placeholder attribute for input elements.
HTML Validator extension for Safari
A couple of days ago, Apple announced support for developing extensions, so I felt obliged to implement my HTML Validator extension for Safari too.
The WebM video format – the saviour of open video on the web?
I don’t think I’m exaggerating when I’m saying something really really important has happened for the future of the Open Web. Finally, it looks like there might be a solution to the video codecs and patent encumbered alternatives we have been dealing with.

It is soon summer (Yay!) and about time for a last Geek Meet before a summer break!
Using HTML5 custom data attributes to store data on HTML elements
When writing JavaScripts for a web page, since the beginning of time, web developers have had the need to store extra data for HTML elements. I remember reading about custom data attributes in HTML5 some time ago, and recently Remy reminded me about them – they are here to save us!
Using the File API for reading file information & multiple file uploads – another sister specification to HTML5
A constant drag when developing web sites have been when the end user wants to upload files to it. Luckily, though, those problems are to come to an end due to the File API.
Using Offline Web Applications to offer offline capabilities – sister specification to HTML5
In a world where we carry our computers/Internet-connected devices with us all around, we’re bound to lose connection now and then but still want to be able to continue our work. That is where Offline Web Applications steps in.

Creating good content mark-up: Content Management Systems vs. hand-crafted HTML
There’s an inner beauty of HTML code that I can never seem to get away from. The wonderful world of semantics – choosing the right element for the right task, something that conveys meaning, makes it more accessible and strikes the perfect balance of different parts of a web page. Which moves us on to Content Management Systems.
HTML Validator extension for Google Chrome
Validating HTML is very important to ensure maximum web browser and operating system compatibility, and making sure it is ready for CSS and JavaScript code to interact with it. Therefore, I have created an HTML Validator for Google Chrome.
Using HTML5 Web Workers to have background computational power
When performing advanced load-heavy operations in a web browser, both the web page it is run in as well as the web browser UI becomes unresponsive till it’s finished. However, there’s a way to address that with HTML5 Web Workers.
What will happen to open video on the web?
With more and more people getting faster Internet connections, and video being one of the ultimate online multimedia experience (so far), it was due to get native video elements in web browsers. However, open video is threatened by codecs and patents, and I thought I’d discuss the situation and possible outcomes here.
postMessage in HTML5 to send messages between windows and iframes
Ever had the need to communicate between windows or the current window and an inner iframe? Across domains as well? I bet you have, but now we have a nice option for doing that!

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.

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.
The HTML5 syntax options problem
Usually blog posts with the words “problem, “considered harmful” and similar are just crying foul, but I would like to bring up something I actually believe is/will become a real problem: HTML5 syntax options.
A faster web with Resource Packages – Mozilla suggestion to have just one HTTP request
One of the most common problem on the web is slow web sites, wasting he time of end users. Now, perhaps, Mozilla has come up with a solution for this, which will be applicable for all web browser vendors.
An introduction to HTML5

Inline Code Finder Firefox extension – find inline JavaScript events, inline styling and javascript:links
When I first coded and released Obtrusive JavaScript Checker, I had some more ideas with it, as well as some great feedback I have received and wanted to see to. The result is Inline Code Finder, which looks for inline styling as well as what the Obtrusive JavaScript Checker offered, and it comes in two versions!
Poll: Do you use access keys?
I felt it was about time to bring up the topic in one of my oldest drafts (written in May 2005) which, for some reason, never saw the light of day.
IE 6: now coming to a cell phone near you
Something was brought to my attention which, to say the least, left me a little baffled: IE 6 is coming to mobile phones…
Why inline CSS and JavaScript code is such a bad thing
Available is also a translation in French of this article.
When I review web sites, and also in my own projects with a number of different team members, I almost constantly stumble across something web developers should really refrain from: inline styling and inline JavaScript code.
Obtrusive JavaScript Checker – Greasemonkey script and Firefox extension to find inline events
In my work, part of it is analyzing both other people’s code as well as my own. Now I have created Obtrusive JavaScript Checker to help me out with that!
CSS includes with the title attribute might be ignored
Yesterday I ran into a little unexpected behavior when adding title attributes to a couple of link elements.
Do we really need Microformats?
A lot of web developers, at least over the years, seem to have fallen for Microformats. Naturally, the given question then is: do we really need Microformats?
Interface Developers have to be available from start to end in a project (and work with real live code)
Having had a number of jobs and from being a consultant, getting the opportunity to see how a lot of companies and clients work over the years, I’m way too often surprised how underestimated cooperation and keeping a competence available throughout a project really is.
Styling BUTTONS, and achieving sliding doors with them
As you all know, form elements aren’t that easy to style, especially not consistently. At a first glance, the button element seems like a sure winner, but once you delve into it…

Explaining semantic mark-up
I have a strong interest in semantics in general, and when it comes to web developing, the benefits of properly marking up a document should not be neglected. One problem is that some people don’t understand the difference it makes, so therefore let me humbly make an attempt to explain why semantics is important.
When did people stop caring about application/xhtml+xml?
Remember a couple of years ago, when serving XHTML with a text/html MIME type was the worst you could do if you were serious about your trade?
Using labels in a nice semantic fashion
It is fairly easy to distinguish a developer’s knowledge level by their usage of label elements. To see how much they care about accessibility, usability and semantics.
Thoughts on HTML 5
People have asked of my opinions about HTML 5 and the road they’re taking. Basically, I feel that you need to do a lot of reading up to actually be eligible to have an opinion, so I’ll try tread lightly with mine, and only cover certain areas.
