CUSTOMIZING THE CLAROLINE PLATFORM A. STYLESHEETS You can customize the Claroline stylesheet by copying the contents of the web/css/classic folder into a subfolder in platform/css. You can then modify the file in this subfolder to adapt the Claroline stylesheet to your needs. B. LANGUAGE FILES You can provide custom language files with custom translation of some language variable by creating a file in platform/lang/NAMEOFLANGUAGE/complete.lang.php For example you can add custom french translations in the file platform/lang/french/complete.lang.php C. TEMPLATES You can personnalize the Claroline templates by copying the files you want to modify from the claroline/inc/templates folder to the platform/templates folder and modify those copies. If you do not follow these instructions you risk to loose all your modifications if you upgrade your Claroline platform !
