Conditional comments for Internet Explorer with Haml

Internet Explorer 5+ is aware of conditional comments Show archive.org snapshot that let you target HTML for selected versions of IE. For example the HTML below would ask users of IE 6 and IE 7 to install Firefox:

Copy<!--[if lt IE 8]>
  <a href='http://www.mozilla.com/en-US/firefox/'>Get a real browser</a>
<![endif]-->

You might wonder how to express such a conditional comment in your favorite templating language, Haml Show archive.org snapshot . You might even have converted a template back to ERB just for this reason! But don't worry any longer, because Haml can do conditional comments Show archive.org snapshot :

Copy/[if lt IE 8]
  %a{ :href => 'http://www.mozilla.com/en-US/firefox/' }= 'Firefox'

Sometimes you may need to insert semi-conditional HTML that is ignored by IE but interpreted by real browsers, like:

<%= stylesheet_link_tag 'screen', :media => 'screen' %>

Such content cannot be expressed in Haml -- you need to open up an :erb section in your Haml file to put it there.
