input 坑

設置input placeholder樣式；

input::-webkit-input-placeholder {
    color: #999999;
    opacity: 1;
}

消去input的黃色樣式

input[type="text"]:-webkit-autofill {
 -webkit-text-fill-color: #fff !important;

transition: background-color 500000s ease-in 0s;
}
#loginPwd:-webkit-autofill {
 -webkit-text-fill-color: #fff !important;
 -webkit-box-shadow: 0 0 0px 1000px #213262 inset; 
 transition: background-color 500000s ease-in 0s;
}
