How do I remove padding to achieve full bleed for an image?

I am trying to have an image on the top of each page that does not have any padding (i.e. the image bleeds right to the edge of the page.  In Site Style, the minimum Site Padding size is 17px and so this is always present.

How do I override the padding so that there is none.

An example page where I am trying to do it is:

https://justgoodjuju.com/bracelets

The image at the top (under the navigation) wants to be right across the page with NO white padding at the right or left.

div#block-yui_3_17_2_1_1562782913306_6143 {
    padding-left: 0;
    padding-right: 0;
}

@tuanphan   Thank You so much - this worked great!
