Q:

how to make disabled input button not ‘grey’ in ios browser?

html
 (input type button disabled), on IPhone devices it's grey!
but I want it stay in the same style when it's disabled...
how to do that?
I tried use “-webkit-appearance: none;” 
all (input type button) changed to my css,
but the disabled buttons is still grey...
even if I write "input:disabled{background-color:white}" 
<style>
input{
    display: block;
    -webkit-appearance: none;
    margin:5px;
    border: 2px solid #000;
    background-color: white;
}

input:disabled{
    display: block;
    border: 2px solid #000;
    webkit-appearance: none;
    background-color: white;
    }
</style>
<body>
<input id="button1" type="button" disabled>

</body>

I want IPhone use the style I write...
