Chrome 26 Beta: Template Element & Unprefixed CSS Transitions
Tuesday, February 26, 2013
Unprefixed CSS Transitions & calc()
CSS Transitions allow CSS property changes to occur smoothly rather than abruptly, as in this demo. The calc() function allows you to use basic mathematical expressions anywhere a length or number is required by a CSS property. Here’s some example code:
Both the prefixed and unprefixed versions of these features will work in today’s Beta, but you should switch to the unprefixed versions after Chrome 26 reaches the Stable channel as we are ending official support for the prefixed versions.
activeTab Extensions API
Chrome extensions let you add custom functionality to desktop versions of the browser. Starting in Chrome 26, the activeTab API allows your extension to interact with the currently active tab when the user invokes your extension - for example by clicking its browser action or hitting a keyboard shortcut. Since the activeTab API requires a user action to activate, it does not cause an install-time permissions warning.
Other new web platform features
The web platform evolves rapidly. In this release, we’ve added the following:
- HTML <main> element can be used to represent the main content of the <body> of a document or application.
- CSS pseudo elements (like ::before and ::after) can now be animated and transitioned.
- Encrypted Media Extensions allow you to play protected audio and video content on the web. See them in action in this WebM demo, and note that they’re not yet available on Android.
- Enable the Experimental JavaScript flag in chrome://flags to try Object.observe(). It lets you add a listener to any JavaScript object that gets called whenever that object or its properties change, as in this simple demo.
MathML has been disabled in order to resolve security and stability issues. In Chrome for Android, we’ve removed support for the datetime <input> type because the spec is still under development. Please use the datetime-local type instead.

Chrome app launcher developer preview
Wednesday, February 20, 2013
You’ll get the app launcher as an icon on your Windows taskbar the first time you install a packaged app. Chrome packaged apps are not yet searchable on the Chrome Web Store - but you can build your own packaged app, upload it to the Chrome Web Store and access it via its direct link.
Try out the app launcher and let us know what you think. If you have any questions or comments, you can use Stack Overflow or chromium-apps. File your bugs and feature requests here.
