Omega theme

add RTL css file

We had the same issue, we needed to have a specific css per language to fine tune the presentation. We also needed this css file to load last. We did as follows:

1. Under the subtheme folder we added a branding folder containg a folder for each language where we added each of the css files. ie. themes/subtheme/branding/ar/styles.css (for arabic), themes/subtheme/branding/zh/styles.css (for chinese), themes/subtheme/branding/en/styles.css (for english) ... etc.

2. Then we modified the template.php file adding the following lines at the end, right before the closing of php ( ?> ):

function subtheme_preprocess_page(&$variables) {
global $language;
// load the specific styles per language
drupal_add_css(path_to_theme() . '/branding/'. $language->language .'/styles.css', array( 'group' => CSS_THEME , 'weight' => 99,'preprocess' => 1));

}

You should replace the 'subtheme' word in the above lines with whatever you called your subtheme.
