纯HTML CSS实现可响应式登陆界面

演示视频

基本思路:

一:日月切换模块

1. 用阴影画出太阳和月亮

2.用transform: translate; transform: rotate;两个属性实现日月交换效果

3.使用<label for="" hidden>标签实现左上角滑块与复选按钮的链接

4.用兄弟选择器“~”实现一个元素对另一个元素的控制

二:注册界面模块

1.使用z-index属性,使注册界面元素全部位于登陆界面之上

2.把注册界面大盒子用clip-path: circle裁剪为一个圆形

3.用<label>元素实现“点我注册”与复选按钮的链接

4.给各元素加过渡效果

5.使用point-event:none属性,使展示注册页面时,底层的登陆界面事件不会生效

其他模块的思路都比较简单,看一下代码和里面的注释基本上就能看懂

具体的实现方法,见下面的代码:
