Not sure how to phrase this question. Let me paint a simple Wordpress setup for single.php:
<div id="container"> <?php the_content(); ?> </div>
But what if, inside the_content(), I want the users to be able to use more advanced page layouts that break outside of the #container? For example, let's say the #container is 1140px wide but I want a blockquote on a page to be 100% width (of the browser)?
Here's a theme that does what I want to do: http://cedarwp.ecko.me/design-patterns-introduction/
Notice how the black bar is full width and would have required html tags to achieve the look.
I think I can do this with shortcodes but that doesn't sound very flexible. Please advise!
