cross browser support matrix
For cross browser support matrices we currently have http://www.quirksmode.org/ as the definitive resource. The problem is that it's not a wiki and has some gaps in it.
Since MDN is becoming a great resource for HTML/CSS/JS/DOM documentation it would be great if each page had a cross browser support matrix.
This doesn't need to be done by mozilla, it can be a community effort. But it would be nice if you can set up some standardized space on pages and a standardized layout for the cross browser support information.
Then the community can fill out all the data as soon as MDN has set up some examples.
Just to be sure, are you happy with this resolution? Were you hoping for one master compatibility table as well?
That's all I needed to see. We'll use those compatibility tables to extend the MDN.
Great idea! In fact, the effort is already under way to add compatibility tables. See https://developer.mozilla.org/en/css/@font-face#Browser_compatibility for an example.
See https://developer.mozilla.org/Project:en/Compatibility_tables for details on how to use templates (macros) to make the tables easier to add and maintain.
