CSS override

Hi;

I create my own ProcessDashboartdSchema page i add some fields

The parent object has CSS file indicated:
define("ProcessDashboardSchema",
    [
        "ProcessDashboardSchemaResources",
        "ConfigurationConstants",
        "RemindingsUtilities",
        "FormatUtils",
        "DesktopPopupNotification",
        "DcmElementSchemaManager",
        "EmptyGridMessageConfigBuilder",
        "QuickFilterModuleV2",
        "css!ProcessDashboardModule"
    ],

I would like to add some CSS tags so i create my new CSS file and try to add it to my new object definition but on page i can see just only settings from CSS indicate in base object.

I would like only increase tom margin of notificationContainer because i add some fields to filterconteiner

Appreciate for any help
