Can anyone tell me what this is:
<!DOCTYPE html>
<!--[if lt IE 7]> <html class="no-js ie ie6" lang="en"> <![endif]-->
<!--[if IE 7]> <html class="no-js ie ie7" lang="en"> <![endif]-->
<!--[if IE 8]> <html class="no-js ie ie8" lang="en"> <![endif]-->
<!--[if gt IE 8]><!--> <html class="no-js iframe" lang="en"> <!--<![endif]-->
I have seen this on so many pages but there is no JavaScript link on some of the pages to support the document declaration.
It seems to be snippet from html5 Boilerplate’s standard format for ‘browser detection’ , see http://html5boilerplate.com/
The section that you have highlighted allows for only one section of the
<html>tag to be parsed depending upon the flavour of browser that the site visitor is using.Read more about this method at the authors website > http://paulirish.com/2008/conditional-stylesheets-vs-css-hacks-answer-neither/
