学了HTML、CSS和JS有了一个月了,JS还未学完,偷懒写一个小项目,用了一个下午,顺便巩固一下所学知识。(内容比较简陋,适合新手)
源代码:https://github.com/yeziyuhai/QQ-login-interface
左边是我的,右边是官方的。没有设计稿和素材,只能自己找,所以是无法做到一模一样的,不够这样子也差不多了。
很明显,简陋的做法是上下两个盒子,中间头像可以定位上面的父级也可以定位下面的父级,这里我选择的是上面,中间内容用一个表单包裹。注册账号和二维码使用定位,父级是大盒子。

思路是渐变45度角倾斜,之后动画改变定位,当然和官方的不一样,做出差不多效果就行。
.css
.login .top {
position: relative;
width: 100%;
height: 40%;
background: linear-gradient(-45deg, #23A6D5, rgba(106, 103, 255), rgba(158, 81, 255), #23A6D5, #23D5AB);
background-size: 400% 400%;
animation: bg 4s infinite linear forwards;
color: #fff;
}
@keyframes bg {
0% {
background-position: 0 50%;
}
50% {
background-position: 100% 50%;
}
100% {
background-position: 0 50%;
}
}
头像绝对定位,顶部相对定位,小绿点绝对定位。
.login .top .head {
position: absolute;
left: 50%;
top: 100%;
width: 50px;
height: 50px;
border-radius: 50%;
border: 2px solid #fff;
transform: translate(-50%, -50%);
box-shadow: 0px 5px 10px 0px rgba(118, 118, 118, 0.4);
background-image: url(/images/head.png);
background-size: contain;
background-repeat: no-repeat;
background-color: rgba(234, 28, 39);
}
.login .top .head .green {
position: absolute;
right: -10px;
bottom: -8px;
width: 14px;
height: 14px;
border-radius: 50%;
border: 2px solid #fff;
transform: translate(-50%, -50%);
box-shadow: 0px 5px 10px 0px rgba(118, 118, 118, 0.4);
background-color: rgba(9, 241, 117);
}
直接搬.less过来,清除一些。这里面挺多细节的,先说好字体大小浏览器最小只能是12px,除非你把自己浏览器最小字号调到10px,视觉上好看一些,不然下面复选框的字会换行。
添加了textChange类,因为需要点击输入框之后样式的改变。
这里耗费我比较多的时间,挺多细节,毕竟我这个人追求完美。
