How to download css for Mediawiki tag extension?

Question

How do you download css for extension?

Using Mediawiki 1.25.2, I copied the boiler plate extension and edited the .json extension to enable

   "Hooks": {
            "BeforePageDisplay": [
                    "FinancialMathematicsHooks::onBeforePageDisplay"
            ],...
    },
    "ResourceModules": {
                  "ext.FinancialMathematics": {
                          "styles": [
                              "modules/ext.FinancialMathematics.css"
                               ]
                     }
      }

and in the hooks file I added

    public static function onBeforePageDisplay( OutputPage &$out, Skin &$skin ) {
            $out->addModuleStyles( 'ext.FinancialMathematics' );
            return true;
    }

but the extension does not include css.

The extension is installed on the wiki here , and the full code for the extension is on github

You should check if the module is loaded correctly. The easiest way is to use the browser console and run the following command:

mw.loader.getState("ext.FinancialMathematics");

error. ( direct load.php url). , Internal Error. , , , .
