Hi Gary,
It's a bit confusing... and different themes deal with it differently. But the underlying concept here that you are missing is that a module must be responsible for a block. So in the case of "block-block-1" it is the block module that is responsible. The menu module (as many other modules) also creates blocks. So you might see "block-menu-1". For each controlling module, the numbering starts over.
But some themes don't use the "delta" or at least not in certain situations. Like I just looked at a site (I think I used Genesis there) where I saw "block-menu-nav" where "nav" was the name of the menu. There was no delta. And on another site using Zen and Panels I saw a block in a panel get "pane-menu-block-1. So now I've confused you. But I think I've gotten you over the hump here, conceptually, yes? A module always "owns" a block.
best,
Shai

I’ve got a CSS problem related to block.tpl.php . I was looking at the API for block.tpl.php, and I’m a little confused over how Drupal assigns the block-block-x ID to come up with block-block-1, block-block2, etc.
From the API: <div id="block-<?php print $block->module .'-'.
$block->delta; ?>" class="block block-<?php print $block->module ?>">
So I see that the ID value comes from "block-<?php print $block->module .'-'. $block->delta; ?>" but where its the numbering controlled?
