 * Hey everyone –
 * I am having a wee issue with referencing a conditional style sheet for IE.
 * I’ve named the stylesheet “ie6.css” and want to add it to function.php, but every
   code I have tried does not work.
 * Here is an example of one of the options I had been trying:
 *     ```
       function ie6_css() { ?>
       <!--[if lt IE 6]>
       <link rel="stylesheet" type="text/css" href="<?php echo bloginfo('stylesheet_directory') ?>/ie6.css" />
       <![endif]-->
       <?php }
       ```
   
 * I have placed ie6.css in the theme’s root directory where the default css resides,
   and have changed some style info to test if it is actually being picked up by
   IE 6 and so far, have had no luck. I am fairly certain the issue is in the above
   code – and likely something I’ve messed up or neglected. I wasn’t sure what to
   put after the function statement, so I put “ie6_css” – not sure if that’s the
   main problem or not.
 * Anyway, does anyone have an suggestions on which code to add to my function.php
   file to get IE to play nice? I really want to target all versions of IE prior
   to IE8 – the site seems fine in IE8, its just IE 6 & 7 that are the issues.
 * Thank you!
 * ~Deirdre

 * Why are you trying to add the conditional comment to functions.php? It belongs
   in header.php – after your calls to the default css file.

 * Because the theme my client installed does not call up the file in the usual 
   way. Regardless, I tried using the standard code (and many variations thereof)
   in the header to pull up the style sheet, and it had no effect. So, while searching,
   I found some information about that theme and it was recommended to use function.
   php to call the CSS.
 * I just logged i to update people in case they had a similar question – I have
   finally met with success. I was using <!–[if lt IE 6]> not realizing that “lt”
   meant versions *less* than 6, not 6 itself – which is why IE6 was not showing
   any change. I replaced the 6 with: <!–[if lt IE 8]> to target versions prior 
   to IE8, and that did the trick.
 * Thanks for the link, I will keep it around for future use.

 * FWIW, `<!--[if lte IE 6]>` = less than or equal to IE6.
