蓝色大气的登陆界面
这是一款使用 Tailwind CSS 制作的目前常见的登陆界面，采用左右两栏布局，左边是背景图和文字介绍，右边是表单，简单却显大气，看起来非常精致、舒服。登陆界面兼容多个尺寸的终端，包括 PC 端，Pad 端和手机端。
下面我们来看看如何制作。

2、CSS
因为使用了 Tailwind CSS，所以我们只需额外再添加一点 CSS 代码即可。
.circles {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
overflow: hidden;
}
.circles li {
position: absolute;
display: block;
list-style: none;
width: 20px;
height: 20px;
background: rgba(255, 255, 255, 0.2);
animation: animate 25s linear infinite;
bottom: -150px;
}
.circles li:nth-child(1) {
left: 25%;
width: 80px;
height: 80px;
animation-delay: 0s;
}
.circles li:nth-child(2) {

animation-duration: 12s;
}
.circles li:nth-child(3) {

}
.circles li:nth-child(4) {

animation-duration: 18s;
}
.circles li:nth-child(5) {

}
.circles li:nth-child(7) {

animation-delay: 7s;
}
.circles li:nth-child(8) {

animation-delay: 15s;
animation-duration: 45s;
}
.circles li:nth-child(9) {
left: 20%;

height: 15px;
animation-delay: 2s;
animation-duration: 35s;
}
.circles li:nth-child(10) {

width: 150px;
height: 150px;
animation-delay: 0s;
animation-duration: 11s;
}
@keyframes animate {
0% {
transform: translateY(0) rotate(0deg);
opacity: 1;
border-radius: 0;
}
100% {
transform: translateY(-1000px) rotate(720deg);
opacity: 0;
border-radius: 50%;
}
}
到这里，我们就制作完了，来看看效果吧：蓝色大气的登陆界面
