下面是一个使用CSS3制作炫酷登录页的示例代码:
HTML部分:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>CSS3炫酷登录页</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<div class="container">
<form>
<h1>Login</h1>
<input type="text" placeholder="Username">
<input type="password" placeholder="Password">
<button type="submit">Login</button>
</form>
</div>
</body>
</html>
CSS部分:
* {
box-sizing: border-box;
}
body {
margin: 0;
padding: 0;
background: #333;
font-family: 'Open Sans', sans-serif;
}
.container {
width: 100%;
height: 100vh;
display: flex;
justify-content: center;
align-items: center;
}
form {
width: 400px;
padding: 40px;
background: #fff;
border-radius: 10px;
box-shadow: 0 0 10px rgba(0, 0, 0, 0.3);
position: relative;
}
h1 {
font-size: 2em;
text-align: center;
margin-bottom: 40px;
color: #333;
text-shadow: 0 2px 2px rgba(0, 0, 0, 0.1);
}
input {
width: 100%;
padding: 10px;
margin-bottom: 20px;
border: none;
border-radius: 5px;
background: #f2f2f2;
font-size: 1em;
color: #333;
}
button[type="submit"] {
width: 100%;
padding: 10px;
border: none;
border-radius: 5px;
background: #2980b9;
font-size: 1.2em;
font-weight: bold;
color: #fff;
text-transform: uppercase;
letter-spacing: 1px;
cursor: pointer;
position: relative;
z-index: 1;
overflow: hidden;
}
button[type="submit"]:before {
content: "";
width: 0;
height: 100%;
background: #3498db;
position: absolute;
top: 0;
left: 50%;
transform: translateX(-50%);
z-index: -1;
transition: all 0.3s ease-in-out;
}
button[type="submit"]:hover:before {
width: 100%;
}
在上面的代码中,我们使用了CSS3的box-shadow属性来添加阴影效果,使得登录框看起来更加立体。同时,我们使用了background属性、border-radius属性和text-shadow属性来美化页面元素。最关键的是,我们使用了CSS3的::before伪元素来创建一个悬浮的蓝色背景,通过动态修改其宽度来实现炫酷的登录按钮效果。
