Opera Browser Standards support chart

By Zi Bin Cheahzibin. Tuesday, March 16, 2010 7:00:00 AM

Opera Mini 5, Opera 10.50, Standards, testing, Opera Mobile 10

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.

* Blur radius is not supported.

† 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.

Good to know. It may be better to have comparison also with other mobile browsers.

dahulevogyre # Tuesday, March 16, 2010 10:02:13 AM

Nice !

So border-radius and box-shadow are supported by Presto 2.3 but not by 2.4 ?
http://www.opera.com/docs/specs/presto23/#css

And why does http://www.opera.com/docs/specs/presto24/ mention css transforms, audio, video and storage ?

Thanks for clarifying !

Zi Bin Cheahzibin # Tuesday, March 16, 2010 11:09:47 AM

dahulevogyre,

In the specifications, it says that Presto 2.5 supports Web Storage and Web SQL storage.

Also, our graphics library "Vega" is in charged of rendering many of the CSS magic in transform and transitions. Part of it is still turned off on the mobile end, hence we see discrepancies such as transform not working in Mobile.

As for video(and possibly audio), we have had it in certain Opera builds since late 2008.http://labs.opera.com/news/2008/07/18/ It was actually Opera that first proposed

Can't wait for 2.5 for the mobile browsers.

When will opera mobile be ready for video HTML5? There is any prediction?

Daniel,

When Opera Mobile moves to Presto 2.5 rendering.

The earlier the better.

Welcome to the Opera Community

Most sites have not made themselves for the Wii. So it may not be possible. Also, Nintendo has not asked Opera to upgrade the Internet Channel yet, so that is fairly old. So, your wish may not be able to be done on your Wii, but it might on your computer

There are still plenty of pages (including YouTube) that work very well using the Wii Internet Channel. Nevertheless I wonder if we will ever see Presto 2.5 on Wii?

I think it already works...but what if it was nearly automatic? Like an all-platform competitor against Xbox media sharing?

There may be an update with the upcoming conference in early June. I've been seeing a few snips about Opera Tablet, and the special Maemo hobby build had an initial port of Presto 2.5 and Carakan. So good news may be close.

Does it means its definitively not included or deactivated or is it kind of working while you don't want to claim support for it?

Cutting Spoonhellspork # Wednesday, June 2, 2010 4:12:16 PM

The official specs for Presto 2.4 indicate features that were supported by Opera 10.x Desktop version. These new charts are for Desktop 10.5x, Mini 5, etc.

Dynamic content mostly does not work in Mini. Period. Site dialog boxes are replicated, and perhaps a similar approach may be used for hover menus eventually.

Mini will never have as many features as Mobile, Devices, Desktop etc. Luckily most dynamic content fares poorly on most mobile devices, so any good website has a failover procedure to support them.

Greg writes: Ditto on the local storage question; the Web SQL is essential for a lot of our work; since the iPhone already has an SQLite engine, it's not clear to me why Opera Mini couldn't build on that. Nowadays, I don't think you get get away with a basic rendering engine; a lot of us generate dynamic content, even for mobile platforms.

Cutting Spoonhellspork # Friday, June 18, 2010 1:22:13 AM

Dynamic and USEFUL? Or just another fringe site with a visual gimmick that breaks when the standard is updated? Opera's hybrid proxy for Mini is very flexible and extensible. No telling what the future holds.

It doesn't hurt that cheap android phones are raising customer expectations. Soon even a very bad phone will be much faster, and we'll see new options and features in Mini. Either that or Mobile will replace Mini as phone hardware improves.

Cutting Spoonhellspork # Friday, June 18, 2010 1:24:51 AM

Followup: Given that Mini is going native on more platforms, there is an exciting possibility: What if the proxy could PRE-COMPILE scripts as native binary for the phone's CPU? Not just off-device compression, off-device formatting, but off-device JIT to deliver speed without the compile/memory hit?

Try going into opera:config and checking your settings.

To the other anonymous commenter, yes "Opera Mobile" can be installed on a computer. As detailed here: http://labs.opera.com/news/2010/04/22/

Found this link in a few seconds:

In my opinion, your 3950 may run javaphone apps, and should be able to run Mini 5.1; running Mobile is unlikely. If you are very lucky, you may be able to use "native" Mini which runs faster and uses less memory.
