Opera Browser Standards Support Chart
Update: see the latest browser support chart listing web standards support for Opera desktop, Opera Mobile and Opera Mini listed here.
Knowing the capabilities of each platform makes a huge difference in creating a great user experience across all platforms and devices. Many of you might be wondering about the capabilities supported on Opera Desktop, Mobile and Mini and how they differ from one another in that regard. We thought it would be nice to provide you with a comparative list of standards support across our three browsers.
Opera 10.5x for Desktop runs on the Presto 2.5 rendering engine, while Opera Mini 5 and Opera Mobile 10 are running on Presto 2.4.
For an engine-specific (and more exhaustive) overview of our standards support, please check out Web specifications supported in Opera Presto 2.5 and Opera Presto 2.4.

† Opera on Windows and Mac support the Ogg container format and the Theora and Vorbis codecs, as well as the WAVE container format and PCM codec. Opera on Linux and FreeBSD supports the container formats and codecs that are installed in the system's GStreamer.
‡ Opera Mini uses the same engine as other Opera products, but it is special as it consists of an Opera Mini thin client on the phone and an Opera Server on the back-end. Because of this particular architecture, Opera Mini does not support asynchronous operations or user interaction such as mouseover events in SVG and Canvas.
¶ Due to Opera Mini's nature as a thin client, Selectors API function calls that require user interaction, such as mouseover events, will not work. The selector queried should also be loaded before the JavaScript that does the querying, which can be done by placing the script just before the body
close tag.
