input 自动填充颜色改变或透明

设置黄色背景变成白色背景：input:-webkit-autofill { box-shadow: 0 0 0px 1000px white inset !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
