html可以使用表单进行的最简单的账号密码登录的页面设计，但是不具备判断账号密码正确性等逻辑的能力，这个需要后台语言处理反馈。
工具原料：编辑器、浏览器
1、使用form表单事件最简单的账号密码登录的数据提交，代码如下：
<!DOCTYPE html><html>
<body>
<form action="login.php">
用户名:<br>
<input type="text" name="firstname" value="请输入账号">
<br>
密码:<br>
<input type="text" name="lastname" value="请输入密码">
<br><br>
<input type="submit" value="Submit">
</form>
</body>
</html>
2、点击提交数据将会提交给login.php进行处理，运行的结果如下：
<!doctype html><html>
<head>
<meta charset="utf-8">
<link href="main.css" type="text/css" rel="stylesheet">
<title>登陆界面</title>
</head>
<body>
<div class="login_ico">
<img src="images/login_ico.png">
</div>
<div class="login_putin">
<ul>
<li><input type="text" ></li>
<li><input type="password" ></li>
</ul>
</div>
<div class="login_btn">
<input type="submit" value="登陆">
</div>
</body>
</html>
样式 ：
*{
margin:0
padding:0}
li{
list-style-type:none
margin:0
padding:0}
a{
text-decoration:none
color:#000}
/*---------------------按钮-----------------------------*/
.login_putin ul li input{

width:70%
padding: 1em 2em 1em 5.4em
-webkit-border-radius:.3em
-moz-border-radius: .3em
border: 1px solid #999
}
.login_btn{

.login_btn input{

}
.login_btn input:hover{
