Beta Channel Arrives for Android Phones and Tablets
2013年1月10日木曜日
Starting today, you can install Chrome Beta channel for phones and tablets on Android 4.0+ from
Google Play
. This release includes some of the biggest developer updates to Chrome for Android since
its launch last year
, bringing many features available on other Chrome versions to Android as well:
With prefixed support for
CSS Filters
you can apply visual effects like grayscale, blur, and contrast adjustment to the mobile web. Try
this demo
on Chrome for Android to see filters in action.
The new
Flexible Box Layout Module
simplifies the styling of complex layouts.
The dynamic
viewport units
vw, vh, and vmin can now be used for responsive design.
The
<track> element for video
provides a simple, standardized way to add subtitles, captions, screen reader descriptions, and chapters. Note that it doesn’t work for fullscreen video on Chrome for Android yet.
The
CSS calc()
function can be used anywhere a length is required by a CSS properties. It allows mathematical expressions with addition (‘+’), subtraction (‘-’), multiplication (‘*’), and division (‘/’) to be used as component values.
The
@sandbox
and
@srcdoc
attributes of the <iframe> element give you more control over inline frames.
Unprefixed
IndexedDB
gives you access to fast, structured client-side storage.
Our technique to make desktop web pages more readable on mobile screens (now called
Text Autosizing
) has been improved and is more consistent with other browsers.
V8 has been updated to 3.15 bringing a big speed boost; performance on the
Octane
benchmark improved on average by 25-30%.
Lastly, the new beta comes with an updated stack of Developer Tools. Expect big improvements in measuring your mobile performance with the Timeline's frames mode and easily navigate and edit your active scripts in the revised Sources panel.
You can report any issues you find within the app or at
mcrbug.com/new
. We’ll be pushing periodic updates so you can test out our latest work as soon as it’s ready. Even better, you can
install the Beta
alongside your current version of Chrome for Android
