it is confusing for sure...Here is what I've noticed...sometimes zip programs tend to goof up the structure on you.
Do this
Create an empty zip folder called "skins.zip" and another called "containers.zip"
Drop all the files related to a skin in the skins.zip and containers into the containers.zip
then create another empty zip folder called whatever you want....skinpackagename, drop both the zip files into the last zip file you made, and viola, it's done.
Here is another way to look at it, by example. if I were makeing a skin I'd do this:
MyCoolSkinname.zip
- contains files:
- MyCool2PaneSkin.html
- skin.css <remind me...are these plural or singlar?>
- skin.xml
- MyCool2PaneSkin.doctype.xml
- contains files:
- MyAwesomeRedH1Container.xml
- container.css <same..not sure if it's plural or not..I think it's singluar >
- container.xml <not sure if this is required...I don't make containers ever really..bought some nice ones >
Anyhow thats kind of the structure it should be...please someone correct me if I'm wrong.
