Header not showing properly on iPhone

Replies: 1

My site is fightforolddc.com
My header shows fine on desktop but not ipad, iphones and androids. This is the code I put into my Custom CSS (I also added color to my background, that part worked):

body{
background-color: #8C001A
}
site-header {
background-image: url(‘http://fightforolddc.com/wp-content/uploads/2015/11/cropped-FFODCBanner2.jpg’);
background-repeat: repeat;
background-position: top center;
background-attachment: scroll;
}

site-container {
padding: 0;
}

site-header-right {
display: none;
}
And it has not changed anything except the background color.
