yes, please add this code

1. Go to Online Store->Theme->Edit code
2. Asset->/timber.scss.liquid->paste below code at the bottom of the file.

#shopify-section-16266671911705cb0b, #shopify-section-1626776660396dd48d {
    margin-top: 0;
}
#shopify-section-16266671911705cb0b .wrapper, #shopify-section-1626776660396dd48d .wrapper {

Thank you! That helped. But there are still these white margins in between. How do I get rid of those?
