D6 anatomy diagram a bit confusing

Technically you are right - since blocks can be placed within the content region. Ideally there should be an additional "brown" block region below the 3 blue nodes in the centre, since blocks placed in the content region sink to the bottom by default.

I've updated the Regions page so I think it is clearer that regions are for content or blocks.

I'm not very good at doing image editing. I agree with #1 that the image should be modified so it says "regions" instead of "block regions", and so that the bottom section of the content region should be brown to indicate that that is also a region where blocks can go.

Can someone who is better at image editing (or who has better tools than I do) make that image edit? If you do not have permission to edit the page, maybe you could edit the image and post an updated image here, and a doc admin can attach it to the page?

Ask dvessel, I think he built those pages and probably has the original images.

I've sent dvessel a message, thanks!

Hello! I know the illustration isn't exactly right. I didn't want to explain visually in exact detail since the overall message could be easily lost. That illustration isn't alone on this either. I was going for the general idea.

If I wanted it to be exact, I'd have to show that the "content" region is special since the content *will always* print out in the page template as $content no matter how the regions are defined from .info. This quirk or special case will most likely be remedied in 7 but for now it's hard to illustrate without making it more visually complex.

Oh, and to be clear, that's why it's labeled as "block region" because the content is never handled through regions. The default settings make it seem like it but it's really not.

But you can add blocks to the Content region...

Yes, adding blocks to the content region is handled through the block system but the page content is completely separate.

The illustration shows that the content area is not a block which is true. It's only when a theme contains a region named "content" that the page body or content merges with any blocks assigned to the region. I know this is confusing but hopefully this issue will remedy that for the next release. #428744: Make the main page content a real block

As far configuring the block admin page, there's no distinction but from a theming perspective they are not the same. I should make that clear in the docs regarding the region settings.

Whoops, I didn't even realize that it was already committed for 7. :)

I updated the notes on the regions handbook page. http://drupal.org/node/171224

Although the previous edits were done with the wrong assumptions, it still applies since any content can be assigned to it through the api function.

I think things are clear enough now. Thanks!
