Are there UI guidelines for facebook canvas apps?

Does Facebook offer guidelines or some kind of CSS style library for Facebook canvas apps? Something that a developer could use to make the look and feel of their canvas app compliment Facebook? I'm speaking along the lines of fonts, colors, dialog box st开发者_JAVA技巧yles, etc.

I guess, in theory, I'm looking for something along the lines of interface builder in iOS development.

Understanding the Platform Policies will help you better design and develop your app. Check the examples and explanations too.

Facebook has published a social design guideline. They also have a brand permissions guideline for when you want to use their logo, colors, etc. But they don't have a specific css/stylesheet guideline like you are asking for.

The following is a link to everything that facebook offers a developer, it does not include any stylesheet guidelines:

The only thing I could think of is when I was implementing Facebook credits, Facebook had guidelines regarding the image to use and a best practice for the flow of purchasing a virtual item with Facebook credits besides that you should be able to develop your app however you like.

You said you where looking for something along the lines of interface builder in iOS development, but I would compare facebook more like the interface builder for Android, everything goes.
