PHP development small forum tutorial login HTML page

Our login page uses a <table> table for layout

Add some simple CSS styles, the final effect is as shown below

## We made a simple JS judgment for the login page. If the username and password are not filled in to log in, relevant prompt information will be given

The specific code is as follows

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>用户登录</title>
</head>
<body>
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>登陆界面</title>
    <script type="text/javascript">
        function foo(){
            if(myform.username.value=="")
            {
                alert("请输入用户名");
                myform.username.focus();
                return false;
            }
            if (myform.password.value=="")
            {
                alert("请输入密码");
                myform.password.focus();
                return false;
            }
        }
    </script>
    <style type="text/css">
        table{
            height: 300px;
        }
        input{
            width: 190px;
            height: 25px;
        }
        .title{
            background-color:#B10707 ;
            color: white;
            border: none;
        }
        .but{
            width: 140px;
            height: 43px;
        }
        .spa{
            margin-left: 10px;
        }
    </style>
