How to reduce the padding on an index page section

Site URL: https://www.cygnetise.com/

Hi I'd like to reduce the padding on an index page within the home page: https://www.cygnetise.com/

The index section is id="what-is-authorised-signatory" 

I want to reduce the spacing between the content box and the margins of the section. Help please! 

Thanks 

Have you got any code making this index section full viewport height?

You can try this Custom CSS:

#what-is-authorised-signatory .Index-page-content {
    min-height:50vh;
}
