Remove padding from code block

I added a code block with HTML and Javascript. Does anyone know how to remove the padding from the code block? 

startstop.site

Try adding to Design > Custom CSS
 

@media screen and (max-width:767px) {
body.homepage .content-wrapper {
    padding-bottom: 5px !important;
}
body.homepage section {
    min-height: unset !important;
}
}
