Add full width wrappers around header, content and footer containers

Change your page.tpl.php file using a subtheme to what you need. The bootstrap docs have a lot of good examples of how to implement their markup.

+1 I actually agree this should probably be in the base theme. I often have to override the tpl file for this as well. Perhaps we can simply add additional wrappers around the header, content and footer containers.

Agree. Fixed width is not of these days anymore.
The real issue I see is the

<div class="main-container container">

in page.tpl.php.
If you combine this with an extra width=100%, you are almost there.
Only problem is the "container" class which should not be on top of a jumbotron.
Removing container class from this div in page.tpl.php results in page width of more than 100%...

Bumping this up to be taken care of in 8.x first.

Forgot to assign.

Sounds good. This is actually a common thing I have to add in when I build a site based off of Bootstrap.

@ryan.armstrong: could you give us a quick workaround/patch of how you get to making it a full page width design - and avoiding the 100+% content? So I can adapt my theme already based on your experience. So we don't have to wait for the next release :-)
Thanks!

This will likely get fixed in 7.x-3.x first.

Dears,
I have same problem with MD Sliders module, where I set it on full width, but it doesn't appear as full width.
Please your support,

Did anyone come up with a pretty good workaround for this?

I'm not entirely sure, but it seems this issue the same as #2260199: Add toggle for .container or .container-fluid in Grid settings which has a patch.

@ryan.armstrong Do you have have the page.tpl.php override that sorts this out?

For anyone still looking for a solution, have a look at http://pixel5.us/node/37

#2260199: Add toggle for .container or .container-fluid in Grid settings provides an "either or" option, but to get both would require customization for whatever region/page you're attempting to do this with. This cannot be accomplished in this project and would ultimately cause major BC breaks.

Maybe this theme config can help you:
