Excellent. I've struggled with this for a long time (and given up). Slim can be a pain sometimes. But I forgive it.

Thanks.

Thanks for the tip. I tweaked the above code to avoid the non-standard un-indented "head" and "body" and also removed the end "html" tag, which is no longer necessary. The advantage of this is that the "html" tag is now in slim, and can be styled (i.e. adding a class or id to the html tag).

doctype html
/[if lt IE 7]
  | <html class="ie ie6 lt-ie9 lt-ie8 lt-ie7">
/[if IE 7]
  | <html class="ie ie7 lt-ie9 lt-ie8">
/[if IE 8]
  | <html class="ie ie8 lt-ie9">
/[if IE 9]
  | <html class="ie ie9">
| <!--[if (gte IE 9)|!(IE)]<!-->
html
  | <!--<![endif]-->
  head
    / various head stuff

  body
    / various body stuff

Even simpler, just use the /! for an HTML comment:

doctype html
/[if IE 8]
  | <html class="ie8 lt-ie9" lang="en">
/[if IE 9]
  | <html class="ie9" lang="en">
/! [if (gte IE 9)|!(IE)]<!--> <html lang="en"> <!--<![endif]
