I’m using a fixed container, and bootstrap is supposed to have a 20px gutter on all sides.
Still, I’m getting no gutter, While Michael Hartl’s layout is OK.

I’m using Chrome on Linux.
Thanks!
EDIT: Found the criminal: But now what?
/* line 9, /.rvm/gems/ruby-1.9.3-p0/gems/bootstrap-sass-2.0.2/vendor/assets/stylesheets/bootstrap/_scaffolding.scss */
body {
margin: 0;
font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;
font-size: 13px;
line-height: 18px;
color: #333333;
background-color: white;
}
Solved by using a custom style – but didn’t solve the bootstrap problem (I’m only overriding it)
Kudos to Sebastian and Terry
