Hello,

This padding is important for all the Woocommerce templates, in order to remove it from the home page you need to add this negative margin to the first section if you use Elementor https://prnt.sc/uhivji or set margin-top:-40px.

The menu is aligned in the center: https://gyazo.com/9e336826440ca7dbf8f2f6103a0f97cc
