autocomplete input color change or transparent

The yellow background becomes white background: 

INPUT: {AutoFill -webkit- 
Box-Shadow: White 0 0 0px the inset from 1000px Important;! 
}  

input:-webkit-autofill:focus {
 box-shadow: 0 0 0px 1000px white inset !important;
}  

设置透明：
input:-internal-autofill-previewed,
input:-internal-autofill-selected {
    -webkit-text-fill-color: #FFFFFF !important;
    transition: background-color 5000s ease-in-out 0s !important;
}

亲测有效
