Banner images not resizing on mobile

I cant seem to get my mobile banners to adjust on mobile. Here is an example of the homepage banner on mobile, ideally I want the image with the logo to be resized/centered.

I have tried inserting this CSS:

@media screen and (max-width:600px)  {.Index-page--has-image .Index-page-content
  {
    width: 100% !important;
    height: auto !important;
  }}

Hi. Add to Design > Custom CSS > Then save & reload your site

/* resize mobile banner */
@media screen and (max-width:640px) {
section#introduction figure img {
    width: 100% !important;
    height: auto !important;
    left: 0 !important;
    min-height: Unset !important;
    min-width: unset !important;
}
section#introduction {
    min-height: Unset !important;
    height: 250px;
}
section#introduction .spacer-block {
    display: none;
}
}

This worked great, thank you! 🙌
