-Webkit prefix is often used by webkit browsers to indicate such features which are still experimental. Opera browsers didn’t support the prefix so far but now, it has confirmed that it has finally started supporting the -webkit prefix. According to Opera, in a way it has been forced to adopt this feature.
Folks at Opera are of the opinion that the a number of websites are using HTML5 and CSS3 features are using in such a way so that only such browsers which support -webkit, such as Chrome, Safari and default iOS and Android browsers, are able to fully use their features. This, on the other hand, makes Opera a lot less desirable for users who wish to make use of these new HTML5 and CSS3 features.
So, precisely because of this, Opera says that it has been forced to adopt support for -webkit prefix. Apparently, developers are increasingly using for -webkit and not for -o. Due to this, the website which are made for -webkit browsers naturally do not look good enough on the Opera browser and Opera suddenly has a huge threat to its presence in the mobile world due to this.
However, this decision may be hailed by some users but yet many others, including analysts, are saying that may lead to further fragmentation on the web. The coders, as Opera claims, has pushed it to adopt the standard. This may lead to Firefox and Internet Explorer too taking similar measures and in a way, being forced to extend support for -webkit.
