Aural CSS notes updated following tests with Opera Voice and FireVoxNovember 18

Opera with Voice and the FireVox extension for Firefox both claim to support some of the CSS 3 Speech module properties. Following some quick tests on Windows, Opera 9.62 seems to work reasonably well, but the latest FireVox appears to have broken support.

jQuery UI accordion: enabling keyboard navigationNovember 4

A couple of weeks back, Karl asked a question about jQuery UI’s Accordion interface widget and keyboard accessibility. I’ve got my head in various JavaScript frameworks at the moment, so I took a quick look.

So, what’s an accordion when it’s at home?

You’ve got an accordion interface when you have a small collection of vertically-stacked, collapsible layers of content that a user can flip between. It’s a similar concept to tabbed interfaces where you view one chunk of content at a time, but in an accordion each of the interface controls are vertical and span the full width of the content. It’s easiest explained with an example (make sure you have JavaScript enabled).

Problems with keyboard accessibility

Karl was finding that, while you could navigate and control the accordion using the keyboard in Safari 3 and Internet Explorer 7, there were problems when using Firefox 3. I’m not yet sure why, but it didn’t work at all for me in Opera 9.6.

dotjay feeds fixedOctober 28

I’ve been aware of a problem with my feeds for a little while. The main feed has been working okay, but some of the others I used to offer went a bit screwy. It should all be fixed again now.

You can subscribe to just my blog entries or to entries with a particular tag. So if you only want to be fed my accessibility posts, you can just subscribe to my accessibility feed. I’ve also included a new lab updates feed. Lab updates will also appear in the main feed. I’ve tried to redirect all previous feed URLs so that they will continue to work. My apologies if they break.
