Layout Team
The layout team is a long-term engineering team tasked with maintaining, supporting, and improving the layout capabilities of the Chromium Blink rendering engine. This includes line layout, block layout, text, fonts, and high-dpi support. It is distinct from style and paint, both of which are handled by their respective teams.
Team Charter
Our overarching goal is to improve the experience for end users and platform developers alike.
- By offering fast, correct, and compatible layout features supporting the majority of writing systems and scripts.
- By providing layered and powerful APIs for developers.
- By driving the layout capabilities of the web forward through collaboration with web developers, other browser vendors, and standard bodies.
- And finally, by intervening when required. Thereby allowing a better user experience for existing and legacy content.
Big ticket items for 2017
- Schedulable, interruptible engine
- LayoutNG can render ~50% of web content.
- Give framework authors the ability to extend the rendering engine
- Ship at least one CSS Houdini API.
- High quality predictable platform
- Maintain bug SLA
- Full test and design doc coverage.
- Ship CSS Grid.
- Unify scrolling implementation (root layer scrolling).
- Ship OpenType variation support.
- Intersection Observer v2.
- Improve rendering performance
- Improve line layout performance by 20%

Bugs & Triage Policy
The layout team is responsible for all bugs marked Cr-Blink-Layout and Cr-Blink-Fonts, including sub-labels. Our policy is that all new bugs are to be triaged within a week of being filed and all P-0 and P-1 bugs are to be fixed in time for the next release. This is a relatively new policy and until we have worked down the existing backlog this only applies to new bug reports while we're working our way through the backlog.
- Bug Triage Instructions
- Untriaged bugs
- Open P0 and P1 bugs
- All open bugs
- Project Warden bugs [legacy]
