How can I make background image show on mobile?

Hi,

Is there any way that I can add code or do something in the style editor that would allow for the silver background image seen on the sides of the desktop version to show up the same way on mobile?

Thank you.

@Ashley4993 Can you share site url & access password?

@Ashley4993 Add to Home > Design > Custom CSS

@media screen and (max-width:767px) {
#header, .outer-warpper {
   max-width: 90% !important;
}
}

I entered it but it didn't do anything.

@Ashley4993 Try this :D

@media only screen and (max-width: 1100px) {
#header, .outer-wrapper {
  width: 90% !important;
}
}

Worked perfectly! Thank you!
