HTML Presentations with Opera

Because Opera is not an extremely popular browser, most developers probably aren’t aware of one of its greatest features: Opera Show mode. Opera Show mode is the official name of the full screen mode for Opera (technically, it’s only called Opera Show when a projection media style sheet – discussed below – is present); and it brings with it a great possibility.

More than two years ago, Opera added support for the projection media mode in CSS. Whenever the browser is expanded to full screen mode, it activates the projection media, allowing you to apply a completely different stylesheet to the full screen page than you have in other settings.

Locating Bugs in Your Javascript Code

If you’re anything like me, you have traditionally used javascript alert boxes to try to identify and diagnose bugs in your javascript code. There are two major issues with this process, though.

  1. It’s extremely inconvenient for your users if you’re trying to debug a live application.
  2. It can be a real problem if you end up in some sort of long/infinite loop and end up outputting multiple alert boxes.

There is a better way, though, and it basically works in Internet Explorer (version 8), Firefox (with the Firebug extension installed), Chrome, Safari and Opera. This is nothing new, by any strecth of the imagination, but it still seems to be a bit of a well-kept secret for a lot of developers.

Opera 9.5 Available

Although it slipped under the radar with everyone getting ramped up for the release of Firefox 3; the folks at Opera released a new version of their browser a few weeks ago. On June 12, Opera 9.5 was released, and apparently includes quite a few updates.
