My theme is adding the following CSS below. How can I remove it? I know that with Drupal 6 you can do
stylesheets[all] = in the .info file but what about Drupal 7? Can
hook_css_alter() be used on an external file?
<link type="text/css" rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css" media="all" />
