On the off chance that this will help someone else out there:

The main trick here is using the pipe character ( | ) to print unprocessed text into your template. Notice that "head" and "body" are both un-indented, because Slim isn't aware of an "html" container element anywhere on the page. That means that you'll need to create your own closing "html" tag at the bottom of the document, not that this is strictly necessary anymore in this day and age, but we want to be neat if we can.

Wow, thank you! I spent about an hour fiddling to try and get this working with Slim, but never quite got where I needed to be. Thank you!

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]
