Homepage Header Margin

Hi,

I am having troubles with the margin on Storefront site. First of all my issue was the header indicating home but I resolved this with the Storefront Title Toggle plugin.

I can’t seem to close the gap between the slider and the HEADER/MENU

I have gone through all the posts and used multiple codes in CSS but none of which are working.

Does anyone know how to close the gap between the header and page content?

Many thanks for you assistance
