I have just seen a webpage whose source code begins with\[code\]</div><!doctype html><!--[if IE]><![endif]--><!--[if lt IE 7 ]> <html lang="es" class="no-js ie6"> <![endif]--><!--[if IE 7 ]> <html lang="es" class="no-js ie7"> <![endif]--><!--[if IE 8 ]> <html lang="es" class="no-js ie8"> <![endif]--><!--[if IE 9 ]> <html lang="es" class="no-js ie9"> <![endif]--><!--[if (gt IE 9)|!(IE)]><!--> <html lang="es" class="no-js"> <!--<![endif]-->...\[/code\]I have seen those IE comments before, in order to fix IE bugs. But what does it mean that \[code\]</div>\[/code\]??Is it a hack or something?
