#Meeting Minutes:

• Part I: Layout API, Worklets
• Part II: Typed OM, Stringification behavior, CR for Paint, Appropriate string representation to use in specified style
• Part III: Next F2F, AnimationWorklet, Serialization of TypedOM, Properties and Values

#Agenda Topics:

Typed OM

• how dead should the style maps be?
• Should StyleValues be immutable?

Properties & values

• revisit the grammar issue. Objects or strings or both?
• introduce custom resources (https://github.com/w3c/css-houdini-drafts/issues/215)
• no-escape parsing mode idea.
• should property deregistration be possible? We don’t allow custom element deregistration.

Layout API

• Update on changes (see current draft) + scope for v1.

Worklet

• Preventing side effects (https://github.com/w3c/css-houdini-drafts/issues/308)
