White space on top of page

If you are talking about the divider element at the very top make sure you set it’s margin top and bottom to 0. This is what I’m seeing in the resulting css:

.elementor-119 .elementor-element.elementor-element-fwwmhit .elementor-divider {
    padding-top: 15px;
    padding-bottom: 15px;
}

Alternatively you could exit Elementor and use the customizer custom css area to paste this:

div.elementor-119 .elementor-element.elementor-element-fwwmhit .elementor-divider {
    padding-top: 0;
    padding-bottom: 0;
}

or

.elementor-119 .elementor-element.elementor-element-fwwmhit .elementor-divider {
    padding-top: 0 !important;
    padding-bottom: 0 !important;
}
