Html制作简单而漂亮的登录页面

先来看看样子。

html源码：

XML/HTML Code复制内容到剪贴板 <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Login</title> <link rel="stylesheet" type="text/css" href="Login.css"/> </head> <body> <div id="login"> <h1>Login</h1> <form method="post"> <input type="text" required="required" placeholder="用户名" name="u"></input> <input type="password" required="required" placeholder="密码" name="p"></input> <button class="but" type="submit">登录</button> </form> </div> </body> </html>

css代码：

CSS Code复制内容到剪贴板 html{ width: 100%; height: 100%; overflow: hidden; font-style: sans-serif; } body{ width: 100%; height: 100%; font-family: Open Sans,sans-serif; margin: 0; background-color: #4A374A; } #login{ position: absolute; top: 50%; left:50%; margin: -150px 0 0 -150px; width: 300px; height: 300px; } #login h1{ color: #fff; text-shadow:0 0 10px; letter-spacing: 1px; text-align: center; } h1{ font-size: 2em; margin: 0.67em 0; } input{ width: 278px; height: 18px; margin-bottom: 10px; outline: none; padding: 10px; font-size: 13px; color: #fff; text-shadow:1px 1px 1px; border-top: 1px solid #312E3D; border-left: 1px solid #312E3D; border-right: 1px solid #312E3D; border-bottom: 1px solid #56536A; border-radius: 4px; background-color: #2D2D3F; } .but{ width: 300px; min-height: 20px; display: block; background-color: #4a77d4; border: 1px solid #3762bc; color: #fff; padding: 9px 14px; font-size: 15px; line-height: normal; border-radius: 5px; margin: 0; }

总结：

复制代码代码如下:<input type="text" required="required" **placeholder="用户名"** name="u"></input>
<input type="password" required="required" **placeholder="密码"** name="p"></input>

placeholder="用户名"的作用:
