Limit the width of primary content wrapper

Totally agree. I will apply a max width.

The max width of 800 that has been applied seems to narrow for certain admin pages such as features, field management, context, views etc... I think it should be wider but will also need take into consideration that there could be a sidebar nav.

Postponing because this affects/is affected by changes to responsive settings in progress in the 2.x branch

I would advise against doing this on a global level since some settings forms are quite wide and only get 'better' with more width. (re: the permissions page)

I do agree it will help the node/edit screens.

Good point. I think the answer is to limit the width of p, text field, text area and a few other form elements and tags so that line length does not exceed the number of characters that starts to hinder legibility. See: http://baymard.com/blog/line-length-readability

That way tables can be as wide as they need to be.

I just committed this:

p, 
blockquote,
pre,
h1,
h2,
h3,
h4,
h5,
h6,
article,
aside,
details,
figcaption,
figure,
footer,
header,
hgroup,
nav,
section,
summary {
max-width: $line-length-normal;
}

And in dimensions.scss in library

$line-length-normal: 85ex;  
/* 
   Optimal text line length for legibility is 65-75 characters. 
   I add an extra 10 to compensate for the fact that ex 
   (the height of the lower case "x", usually equal to it's width 
   and therefor an average character) is narrower than the width of 
   an uppercase letter and any given line will contain a few of them.
   Apply in the style.scss file using "max-width"

@tkoleary since you already made the commit, this can be considered fixed.

If we have CSS that needs testing, a patch should be posted and the 'needs review' status can be used.
