Animatable pseudo-elements, seamless iframe fixes and Happy 2013!

Published on January 8th, 2013 in Uncategorized.

Happy New Year! This update briefly talks about the 613 changes which landed in Chromium and WebKit last week, as many people were still on holiday.

After refactoring work for moving the ::before and ::after pseudo-elements in to the DOM, Eliott enabled support for CSS animations and transitions on these pseudo-elements. When using a keyword as the timing function for a transition WebKit will no longer return a cubic bezier and re-layouts for Flexible Box elements when using overflow, paddings and absolute positioning has been fixed.

Mike made sure that bodies of seamless iframes default to having no margin and that seamless iframes with content specified through the @srcdoc attribute will now inherit styles. Furthermore, the prefixed webkitPostMessage has been removed from all WebKit ports in favor of the unprefixed version.

Other notable changes include:

Sheriffbot is now able to tell #webkit who the active Chromium gardeners are.
An Objective-C API for JavaScriptCore has been added.
The EFL port enabled support for MHTML archives and the <template> element.
The first steps towards having a solid sandbox for 64-bit Chromium for Windows have been taken.
Nico wishes you a happy 2013!

Surely there’ll be more interesting updates next week again :--).

Win 64 optimized chrome would be soo cool 😀

Hi Peter,

I’ve wrote to you before about new canvas things – well, I noticed recently that Chrome has support for dashed/dotted lines so I’v written an article about it here if you’re interested:

Cheers!

Wow, seamless iframes are groovy–I’d heard they were being spec’d but didn’t know they’re actually available in Chromium in some form. (Styles seem to inherit, at least.)

Peter, thank you for all your work. As a web developer, I am following you and Paul Irish for some time. And all the good stuff you guys get into devtools is just amazing and well appreciated. Love reading about pseudo adding to the dom, debugging those items always been painful. Regards

Would love to see an update to your site – hope things are going OK. I love to see how Chrome is becoming an ever richer platform for content and your updates are the best place to get that info (except trawling through the changelogs!).
