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.

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.

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!

You have probably seen this elsewhere on the web, read me go on about it on Twitter, or something, but I thought I’d go through what I find to be some weird and provoking marketing strategies from Microsoft recently.
