safari - CSS gradient not working on iOS

Question

I have created a gradient background using a CSS generator. This works perfectly in all major browsers and on Android. However in iOS i get this.

What do I need to add to this gradient in order to make it working on iOS?

Edit: Because this question isn't gaining enough attention, I'd like to ask a different question: What do I need for css tag to create a linear gradient for safari/ios, when, as in this case, -webkit-linear-gradient is not working? Are there any other css gradient tags, specifically for safari?

Here's the code for my background:

.gradient {
/* Legacy browsers */
background: #FF7701 url("gradient-bg.png") repeat-x top;
-o-background-size: 100% 100%;
-moz-background-size: 100% 100%;
-webkit-background-size: 100% 100%;
background-size: 100% 100%;
/* Internet Explorer */
*background: #FF7701;
background: #FF7701/;
filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src="gradient-bg.png", sizingMethod="scale");
}
@media all and (min-width: 0px) {
    .gradient {
        /* Opera */
        background: #FF7701 url("gradient-bg.svg");
        /* Recent browsers */
        background-image: -webkit-gradient(
            linear,
            left top, left bottom,
            from(#FFAD26),
            to(#FF7701),
    color-stop(0.5, #FEA026),
    color-stop(0.5, #FFFFFF),
    color-stop(0.5, #FFFFFF),
    color-stop(0.5, #FFFFFF),
    color-stop(0.5, #FF8B00)
        );
        background-image: -webkit-linear-gradient(
            top,
            #FFAD26,
            #FEA026 50%,
    #FFFFFF 50%,
    #FFFFFF 50%,
    #FFFFFF 50%,
    #FF8B00 50%,
    #FF7701
        );
        background-image: -moz-linear-gradient(
            top,
            #FFAD26,
            #FEA026 50%,
    #FFFFFF 50%,
    #FFFFFF 50%,
    #FFFFFF 50%,
    #FF8B00 50%,
    #FF7701
        );
        background-image: -o-linear-gradient(
            top,
            #FFAD26,
            #FEA026 50%,
    #FFFFFF 50%,
    #FFFFFF 50%,
    #FFFFFF 50%,
    #FF8B00 50%,
    #FF7701
        );
        background-image: linear-gradient(
            top,
            #FFAD26,
            #FEA026 50%,
    #FFFFFF 50%,
    #FFFFFF 50%,
    #FFFFFF 50%,
    #FF8B00 50%,
    #FF7701
        );
    }
}

In mobile Safari at least, you can't use the keyword transparent, you have to use rgba(255, 255, 255, 0) instead.

This is described here: https://developer.apple.com/library/safari/documentation/internetweb/conceptual/safarivisualeffectsprogguide/Gradients/Gradient.html

As you can see, even in Apple's own official document, rgba(255, 255, 255, 0) is used instead of transparent.
