I want to load a custom css file for the admin panel from a custom module folder.

My layout xml file looks like this

<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
        <css src="Vendor_Module::test.css" />

I've also tried

    <css src="Vendor_Module::css/test.css" />

I tried putting the file in




After each I cleared the cache, the page cache and the pub/static folder.

The css file is not loading. Does anyone know why ?

    Assuming that your module is enabled, try running bin/magento setup:upgrade Feb 23 '16 at 12:49
  • that worked... so php bin/magento setup:static-content:deploy is not enough.... do I have to run setup:upgrade every time i add new js or css file to a module ? Feb 23 '16 at 13:08
  • I'm not sure, but bin/magento setup:upgrade always seem to solve my issue Feb 23 '16 at 13:12
  • ok, 10x. one more question. When I write in a js file from a certain module, I always have to clear pub/static and regenerate full static content so I can check what I've done, how can I escape that on development mode ? Feb 23 '16 at 13:14
  • According to devdocs.magento.com/guides/v2.0/config-guide/bootstrap/… development mode should not cache those files Feb 23 '16 at 13:17

Assuming that your module is enabled and configured correctly


bin/magento setup:upgrade
