Create a responsive mobile theme based on a default theme

What’s in this topic

The topic describes how to create a responsive mobile-specific theme using the default Magento approaches.

Creating a mobile-specific theme

To use all the responsive approaches implemented in the Magento out-of-the-box Blank and Luma themes, your theme should declare one of them as a parent.

To create a mobile-specific theme:

  1. Create a theme as described in Create a theme, having specified Blank or Luma as a parent theme.
  2. Add a <theme_dir>/Magento_Theme/layout/default_head_blocks.xml layout file with the following content:
<page xmlns:xsi="" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
        <remove src="css/styles-l.css" />

This will remove the desktop-specific files from your theme.
