Reduce space between header and image block

Site URL: https://www.feelgoodbox.co.uk/

Hi,

I am looking to reduce the spacing between the header of my webpage and the first image block below (marked in red), I have had a look on the forum and tried some of the code I have found but it does not seem to work. I am using the hester template and it is 7.1

I would probably want to reduce that gap by 50& or 75% if possible.

Feel free to let me know if you need anything else.

[data-section-id="5f5a8a2bf78f8a4f7f9b57cb"] .content-wrapper {
    padding-top: 0 !important;
}
