实现思路1：如果不是想设置为透明色 可直接使用box-shadow

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

实现思路2：关闭自动填充功能 ( 也可实现 不推荐 )

<input type="text" autocomplete="off">

实现思路3：通过CSS3动画解决

input:-webkit-autofill,
    input:-webkit-autofill:hover,
    input:-webkit-autofill:focus,
    input:-webkit-autofill:active {
        -webkit-transition-delay: 111111s;
        -webkit-transition: color 11111s ease-out, background-color 111111s ease-out;
    } 

代码示例

    .entername>.el-input__inner{
        border: none;
        line-height: 38px;
        padding-left: 10px;
        padding-right: 0;
        background: transparent; 
        color:#ccc
    }
    .enterpassword>.el-input__inner{
        border: none;
        line-height: 38px;
        padding-left: 10px;
        padding-right: 0;
        background: transparent;
        color:#ccc
    }
     .entername>.el-input__inner:-webkit-autofill,
     .entername>.el-input__inner:-webkit-autofill:hover,
     .entername>.el-input__inner:-webkit-autofill:focus,
     .entername>.el-input__inner:-webkit-autofill:active {
        -webkit-transition-delay: 99999s;
        -webkit-transition: color 99999s ease-out, background-color 99999s ease-out;
    } 
     .enterpassword>.el-input__inner:-webkit-autofill,
     .enterpassword>.el-input__inner:-webkit-autofill:hover,
     .enterpassword>.el-input__inner:-webkit-autofill:focus,
     .enterpassword>.el-input__inner:-webkit-autofill:active {
        -webkit-transition-delay: 99999s;
        -webkit-transition:  color 99999s ease-out,background-color 99999s ease-out;
    }
