I have some css to place a background image within a div with a linear gradient like so:
background-image: linear-gradient(rgba(0, 0, 0, 0.5), rgba(0,0,0,.15)), url(image.jpg);
background-position: center;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
Yet nothing shows at all on iPad or iPhone. I've looked at a few other questions (Background image not showing on iPad and iPhone, CSS gradient not working on iOS) but haven't successfully been able to put it together.
How can I achieve this?
