I have tried adding conditional CSS in Responsive Bartik and also a custom subtheme of Responsive Bartik with no success:

/*A*/
function responsive_bartik_preprocess_html(&$variables) {
  // Add conditional stylesheets for IE
  drupal_add_css(path_to_theme() . '/css/lte_ie8.css', array('group' => CSS_THEME, 'browsers' => array('IE' => 'lte IE 8', '!IE' => FALSE), 'preprocess' => FALSE));
}

/*B*/
function responsive_bartik_preprocess_html(&$variables) {
  drupal_add_css(drupal_get_path('theme', 'responsive_bartik') . '/css/lte_ie8.css', array(
    'group' => CSS_THEME,
    'browsers' => array(
      'IE' => 'lte IE 8',
      '!IE' => FALSE
      ),
    'preprocess' => FALSE
  ));
}

I have also tried to add this to .info-file
C
ie_stylesheets[screen][lte IE 8][] = css/lte_ie8.css

For now I am not sure if this is a bug report or support request. Feel free to change category if there is a working solution for this. (I would like to avoid using another module.) I have used solution A several times in other D7 themes like Bartik without problems.

(Using Drupal 7.25)

I cannot reproduce this problem. The following code appears to work correctly:

drupal_add_css(path_to_theme() . '/css/lte_ie8.css', array('group' => CSS_THEME, 'browsers' => array('IE' => 'lte IE 8', '!IE' => FALSE), 'preprocess' => FALSE));
