    This method works, with the closing html tag: 

    !!! 5
//if lt IE 7
    <html class="no-js lt-ie9 lt-ie8 lt-ie7">
//if IE 7
    <html class="no-js lt-ie9 lt-ie8">
//if IE 8
    <html class="no-js lt-ie9">
// [if gt IE 8] <!
html(class="no-js", lang="en")
    // <![endif]
    head
        title= title

    body!= body

    Update:

    As pointed out by kumar-harsh this behaviour has now been depreciated, if you need this functionality you now should use regular html:

    <!--[if IE]>
  <html class="ie">
<![endif]-->
<![if !IE]>
  <html class="not-ie">
<![endif]>
</html>

    Very simple.

    Exemple:

    HTML

    <!--[if lt IE 7 ]><html class="ie ie6" lang="en"><![endif]-->
<!--[if IE 7 ]><html class="ie ie7" lang="en"><![endif]-->
<!--[if IE 8 ]><html class="ie ie8" lang="en"> <![endif]-->

    JADE

    //[if lt IE 7]>
  <html class="ie ie6" lang="en"> <![endif]
//[if IE 7]>
  <html class="ie ie7" lang="en"> <![endif]
//[if IE 8]>
  <html class="ie ie8" lang="en"> <![endif]

    as far as i know you can not put html tags like this in jade. for this either you need to include an html or by using trailing (.) in tags which supports text like:

    p. <html><script></script>....

    So html tag does not support text so you cant do it. the other solution is:

    -if IE==6
    html.ie6
-if IE==7
    html.ie7
-if IE==8
    html.ie8
-if IE==9
    html.ie9
  head
  body

    In version 1.0.0 (released on 22 December 2013) Jade does not parse comments content any more and support for the IE conditional comments has been removed (//if lt IE 7 will not work as in version 0.35.0 and below).

    The new approach is to use well formatted IE conditional comments. So in order to generate above IE conditional comments, Jade template will have to be as follows:

    <!--[if lt IE 7 ]> <html class="ie6"> <![endif]-->
<!--[if IE 7 ]>    <html class="ie7"> <![endif]-->
<!--[if IE 8 ]>    <html class="ie8"> <![endif]-->
<!--[if IE 9 ]>    <html class="ie9"> <![endif]-->
<!--[if (gt IE 9)|!(IE)]><!-->
html(class="") 
  <!--<![endif]-->
  ...

    Note that the first four html elements are well formatted HTML elements. The last one uses Jade syntax. Also the last comment <!--<![endif]--> has to be indented.

    With Jade version 1.0.0 and above it is safe to use HTML comments as Jade will ignore any line beginning with < character.

    You can also visit this post on IE Conditional Comments in Jade which talks about difference between Jade version 0.35.0 and 1.0.0. It also shows alternative approach of using Jade mixins mechanism for conditional comments.

    This is what you're looking for, and it will also give the closing html tag.

    !!! 5
//[if lt IE 7]><html lang="en" class="no-js oldie lt-ie9 lt-ie8 lt-ie7"><![endif]
//[if IE 7]><html lang="en" class="no-js oldie lt-ie9 lt-ie8"><![endif]
//[if IE 8]><html lang="en" class="no-js oldie lt-ie9"><![endif]
//[if gt IE 8]><!
html(class='no-js', lang='en')
  //<![endif]
  head

    Starting at version 1.0.0, the // if construct is not magical anymore. Either render HTML verbatim (any line starting with < is transmitted as-is by Jade) or use a mixin, as per Tom's blog cited in another answer:

    mixin ie(condition)
    | <!--[!{condition}]>
    block
    | <![endif]-->

doctype html
html
  head
    title= My title
    +ie('if IE 8')
      link(rel='stylesheet', href='/stylesheets/style-ie8-1.css')
