The Platform Layout Team is primarily responsible for [http://en.wikipedia.org/wiki/Gecko_%28layout_engine%29 Gecko's] style system and layout engine.

== Triage Process & Guidelines ==
 
If you're curious about how we triage and prioritize bugs, please visit [[Platform/Layout/Triage|our triage page]] for more information. This page includes information about our triage process and guidelines, as well as useful triage and backlog related bug queries.
 
== Whiteboard Tags ==
 
We use the following strings (tags) in the whiteboard field on bugs in Bugzilla to track important metadata:
 
* <code>[layout:backlog]</code>: Indicates the bug is in our backlog, and is either under active development, or planned development for the current year (see bug priority for approximate timeline).
* <code>[layout:icebox]</code>: Indicates a bug we are considering including in our backlog in the future, but are unlikely to work on in the current year.
* <code>[layout:triage-discuss]</code>: Indicates that we plan to discuss this bug in more detail at one of our internal, bi-weekly triage meetings. Usually this is set if the severity level is disputed, or in question, or other triage details of the bug are unclear.
