Play with the new Opera engine

December 4, 2008 · by EspenAO

Here are quick links to some of the cool topics covered in the Dev.Opera article by Chris Mills.

Note that this alpha release is not intended to show off the full feature set of Opera. It is the first public release of the Presto 2.2 rendering engine, which will be present in Opera 10, made available so you can start trying out some of the new web technology support. You need to use the Opera 10 alpha build to access the below examples, otherwise they won't work.

Web fonts

Web Fonts is a CSS 3 module that allows you to specify a location to download a specified font from, if it is not available on a site visitor's computer.

Opacity through RGBA and HSLA

In Presto 2.2 it is easier to make page elements transparents.

Fast forward by mice, where's it =(
It's the best feature that i like in Opera

A friend of mine doesn't meet this problem, maybe she upgrade to Opera 10, just not uninstall Opera 9 and do a new installation like me. I guess that. However, when i uninstall Opera 10 and re-install Opera 9, the feed function doesn't work, so i have to try Opera 10 once again to not lose any feeds of mine

I think the team of ours should add a new feature : back feed up (not feed list). There're some feeds so useful and with any new installation (no back profile up), i always lose any feeds of mine =(

Still =( I got another hopeless (with my new installation, not upgrade) : when i press Ctrl + Tab to switch between tabs, there's no highlight to show me which tab is chosen. So with about 10 tabs or more is opened, how can i know which to choose ?

=( bad feelings at the first time

Great job Opera. Opera 10 is faster than my Internet Explorer browser and Firefox as well. Opera 10 gets live stream videos connected and running quicker than the other two browsers. Congratulations Opera. I'm un-installing my other browsers.

Great job! I remember the first alpha of the Firefox and I was surprised with speed and stability of this alpha.

Thank you, Opera Software ASA. The future of the Web is in your hands.

I have used and tried many browsers. IE8 can not compete. The newest Firefox, in Minefield, will be a major competitor, since so many add ons are available via Firefox. I like Flock, based on the Firefox 3 platform,as a social browser and Safari is also interesting and quick with great color renditioning. Now there is this version of Opera which seems to have it all and the rest will need to play catch up. As developers get to play with this system's options, I expect users will love the results. The speed is impressive, and light weight<size wise> in my computer as well. And to think this is just the Alpha build...
