Effects Task Force

The CSS and SVG Working Groups have formed this Effects Task Force (FXTF) to work on joint issues that affect both technologies. The goal is to have consistent underlying models even where there is different syntax.

The FX Task Force is a public group.


This task force is chartered as a public group.


The FX taskforce has teleconferences Mondays 21:00 - 22:00 UTC every other week, for the exact schedule see the W3C Teleconference page (GA_FXTF).
