Opera has confirmed that they will begin supporting the -webkit prefix in their web browser, according to FarukAt.es.

The -webkit prefix is normally only used by webkit browsers to denote experimental features.

Their argument, roughly summed up, is that too many websites have started to take advantage of new HTML5 and CSS3-features in a way that only benefits those users with WebKit-based browsers-Chrome, Safari, and every iOS and Android device's default browser-and that the authors of those websites have done a "lazy" job not including a standards-compliant version of features.

Basically, Opera is complaining that developers are coding for -webkit and not using -o. So, when a site is viewed in the Opera browser it doesn't look correct.

While this decision might make some sites look better in Opera. It's not necessarily a good change.

Opera's precedent is opening the door for Mozilla (Firefox) and Microsoft (IE) to do the same, meaning that for authors-the group already accused of being too lazy to do the right thing-the Web is about to become an ever-more fragmented mess, where the once-safe experimental feature known as -webkit- (and -moz- etc.) now will come to represent a much more fragile, questionable feature or implementation.
