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\0/;
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
        );
    }
}

Answer 1

Do give this a check in iOS but it ought to work:

background: #ffad26; /* Old browsers */
background: -moz-linear-gradient(top,  #ffad26 0%, #fea026 50%, #ff8b00 51%, #ff7701 100%); /* FF3.6+ */
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#ffad26), color-stop(50%,#fea026), color-stop(51%,#ff8b00), color-stop(100%,#ff7701)); /* Chrome,Safari4+ */
background: -webkit-linear-gradient(top,  #ffad26 0%,#fea026 50%,#ff8b00 51%,#ff7701 100%); /* Chrome10+,Safari5.1+ */
background: -o-linear-gradient(top,  #ffad26 0%,#fea026 50%,#ff8b00 51%,#ff7701 100%); /* Opera 11.10+ */
background: -ms-linear-gradient(top,  #ffad26 0%,#fea026 50%,#ff8b00 51%,#ff7701 100%); /* IE10+ */
background: linear-gradient(to bottom,  #ffad26 0%,#fea026 50%,#ff8b00 51%,#ff7701 100%); /* W3C */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#ffad26', endColorstr='#ff7701',GradientType=0 ); /* IE6-9 */

I'd also recommend looking into a pre-processor like SASS which will generate a lot of these things for you.

Alternative 1

As an alternative, you could try using an inset box shadow. It's not exact, and it has it's limitations but it's just an option :)

background-color:#FF8B00;
-webkit-box-shadow: inset 0px 100px 0px 0px rgba(255, 255, 255, 0.5);
box-shadow: inset 0px 100px 0px 0px rgba(255, 255, 255, 0.5);

Alternative 2

If you know the height, either use the box shadow above or just use a background image. That way you'll get cross-browser support without the mess that is a hundred prefixed CSS properties like above :)

Answer 2

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.

And its iPhone screenshot...

add your css class to the element.

HTML

<div data-role="page">

    <div data-role="header">
        <h1>Page Title</h1>
    </div><!-- /header -->

    <div data-role="content">

       <div class="ui-grid-a">
           <div class="ui-block-a"><div class="ui-bar gradient" style="height:200px">Block A</div></div>
            <div class="ui-block-b"><div class="ui-bar gradient" style="height:200px">Block B</div>
       </div>

</div><!-- /grid-a -->

    </div><!-- /content -->


</div><!-- /page -->
