Magento

I’m trying to separate the title of the section from the rest of the content.

Where is the ‘content’ coming from in the statement: <?=$this->getChildHtml('content')?>

I have the same question:

<?php echo $this->getChildHtml('content') ?>

Where is its template?

I think it is in template\page\template\container.phtml, but I´m confusing.

Any help?

Everything in the catalog (product grid/list view) and product page (not including left/right sidebar) and anything you insert to CMS page go into content. 

Use template path hints to look for files - search “template path hints” if you don’t know what it is.
