Hero image white space on both sides

Hello,
On https://www.drphysio.gr/θεραπεία-με-winback-tecar/ hero image has white space on both sides (desktop/mobile/tablet view).
How to stretch it to full screen?
Thank you in advance!

Hello there,

Try adding this CSS code to Appearance > Customize > Additional CSS from dashboard.

    @media only screen and (max-width: 780px) {
      #pgc-3170-0-0 {
        padding-left: 0 !important;
        padding-right: 0 !important;
      }
    }

This does not do anything…there is still white space on both sides
