I am beginner in magento 2, I want to add a style CSS for my Block but it does not work, here is the code:

    <css src="Managys_Pricing::css/style.css"/>
<update handle="editor"/>
    <referenceContainer name="content">
        <block class="Managys\Pricing\Block\Adminhtml\Configuration\Edit" name="pricingadmin_configuration_edit"/>
    <referenceContainer name="left">
        <block class="Managys\Pricing\Block\Adminhtml\Configuration\Edit\Tabs" name="pricingadmin_configuration_edit_tabs"/>

At the level of Block\Adminhtml\Configuration\Edit\Tab I added column_css_class

                'label' => __("Dernière mise à jour des prix   :"    .$configuration["last_price_update"]),
                'column_css_class' => 'date_update'


And I put in the css file,

width: 500px;

enter image description here

I do not know if as the continuation or no. Thank you to help me!

Store your Css in


Ans Store js in


in your layout

<!-- for css file -->
   <css src="Vendor_Module::css/grid.css"/>

   <!-- for js file -->
   <script src="Vendor_Module::js/grid.js"/>

then run comand => php bin/magento setup:static-content:deploy

  • I run this comand php bin/magento setup:static-content:deploy but it appears an error: NOTE: Manual static content deployment is not required in "default" and "de veloper" modes. In "default" and "developer" modes static contents are being deployed autom atically on demand. If you still want to deploy in these modes, use -f option: 'bin/magento set up:static-content:deploy -f
