I’m writing about the CSS3 Multi-column layout module and I notice that WebKit supports a series of proprietary properties: –webkit-column-break-after, –webkit-column-break-before, and –webkit-column-break-inside. However, despite the documentation saying that they’re implemented in Safari 3+, I can’t seem to get any of them to work.

Has anyone reading this ever seen an example of these in action? I’ve searched for demos but have found nothing. If you know anything about this, please leave me a comment; your help would be gratefully appreciated.

The Opera team have released a very early preview of their next browser, which features an updated version of their Presto rendering engine. Opera 10.5 will support CSS transforms and transitions, so I’ve updated the demos on my old post, Anime with CSS and WebKit, to reflect that.

Last month the W3C released a working draft of the File API, which defines the basic representations for files, lists of files, errors raised by access to files, and programmatic ways to read files. The Firefox team have already implemented much of it, and have released a series of impressive demos on hacks.mozilla.org, which you can see if you have a recent beta of Firefox 3.6 (or a nightly trunk build).

The four demos shown to date display different (although related) aspects of the API, showing first multiple file uploads, then a drag and drop upload interface, next adding progress information (although this doesn’t work for me), then reading EXIF data from a JPEG image. You can imagine how these combined would be used for native drag and drop uploading to Flickr, for example.

The File API plays a big part in integrating the browser more tightly with the OS, particularly when combined with the drag and drop functionality, and I’m sure it’s only a matter of time until the other browsers implement this. Congratulations to the Firefox team for their work on this, and hacks.mozilla.org for some great demos.

In the first part of this post I gave a potted history of the differing syntaxes, and provided an overview of how that affected linear gradients. In this second part I’m going to look at radial gradients.

Here the syntaxes diverge slightly more, with WebKit requiring more values than Mozilla; while that adds some flexibility, it also increases the complexity.

CSS Gradients were originally proposed by the WebKit team in April 2008, modified from the syntax proposed for the Canvas element of HTML5. In August of this year, Mozilla announced that an implementation slightly modified from that of WebKit would be in the next version of Firefox (3.6).

Since then, however, the CSS WG have discussed a different syntax, and a resolution was passed to add this to the Image Values module. Mozilla have decided to implement the new syntax, which is simpler than WebKit’s but less flexible.

In this article, which will be split into at least two parts, I’m going to compare the two syntaxes.

With the rapid growth of the mobile web, location-aware services are very much in-demand; the GeoLocation API was proposed to cater to this need.

Implementation is spotty at the moment; Firefox 3.5 supports it, as does Safari for iPhone (although not on the desktop, AFAICS). But it’s so simple to use, I’ve no doubt it will be adopted rapidly.
