javascript usage in html tag

Question

<!--[if lt IE 7]>      <html class="no-js lt-ie9 lt-ie8 lt-ie7"> <![endif]-->
<!--[if IE 7]>         <html class="no-js lt-ie9 lt-ie8"> <![endif]-->
<!--[if IE 8]>         <html class="no-js lt-ie9"> <![endif]-->
<!--[if gt IE 8]><!-->
<html class="no-js">
<!--<![endif]-->

what does this mean? why are they applying it only to IE(internet explorer)?

This query was introuced by Microsoft, for cross browsing. Fortunatly it wasn't taken by W3C. So it does exists only in IE. — Reporter, Oct 13 '14 at 15:41
Sorry, I think I actually misread your question. Are you talking about the comment conditionals or the `class="no-js"` attribute? — Gohn67, Oct 13 '14 at 15:42

There is no JavaScript there.

Those are conditional comments: a hack supported by old versions of IE that misapplied HTML's comment syntax to do browser detection.
