关键技术点
程度垂直居中
首先把须要居中元素的容器设置高度,而后设置元素的 top、left 属性为 50%,最初应用 transform 拉回元素的 50% 宽高,另外肯定要设置 position 属性为 relative。
html, body, .container{height: 100%;}
.login-wrapper{
position: relative;
left: 50%;
top: 50%;
transform: translate(-50%, -50%);
}
文本框去掉轮廓线
未去掉轮廓线的文本框的成果如下图
去掉轮廓线的文本框的成果如下图
outline: none;
文本框禁止显示历史输出内容
<input type="text" autocomplete="off" />
