I'm really new to magento and was asked to remake our old theme (shopify store) in magento. I've chosen to create a theme without a parent so i could have more control, following this tutorial to create it https://devdocs.magento.com/guides/v2.4/frontend-dev-guide/themes/theme-create.html
This all works fine, but now i don't know how to go on from here, do i need to start creating new layouts or can i just start adding css to the theme. (I only need to remake the header and footer.)
Also, how can i remove or hide the unwanted sections like newsletter signup for example?
Thanks in advance!
