1Back up your theme (Online Store > Themes > Actions > Duplicate) before changing any code.
2Open Online Store > Themes > Edit code and create a new file under Sections using the file name shown above.
3Paste the complete file - markup, styles and JavaScript are already inside the single file, nothing else to install.
4Open the theme editor, add the section to a template, and replace the example values using the section settings.
5Preview the storefront and test it on a phone-sized screen before publishing.
