Question

Using

gem 'bootstrap-generators', '~> 2.0'
gem 'simple_form', '~> 2.0'

Bootstrap style is non-existant in IE9 and under, but shows fine in IE10 via http://netrenderer.com/.

my bootstrap-generators.css.scss:

@import "bootstrap-variables";

body {
  padding-top: $navbarHeight + 20px;
  padding-bottom: 40px;
}

.page-header {
  a.btn {
    float: right;
  }

  a.btn + a.btn {
    margin-right: 8px;
  }
}

@import "scss/bootstrap";
@import "scss/responsive";

Any thoughts?

The cause is described here Rails 3.1, assets pipeline and IE 6 & 7 in production mode – some CSS & js are not loaded properly

We had to split up the css, and now all works fine.
