   <!DOCTYPE html>
   <html lang="zh">
   
   <head>
       <meta charset="UTF-8">
       <meta name="viewport" content="width=device-width, initial-scale=1.0">
       <title>CASIO 计算器</title>
       <style>
           td {
               border: 1px solid #000;
               height: 40px;

               font-size: 18px;
               background-color: #fff;
           }
       </style>
   </head>
   
   <body>
      <table width="200" height="30" border="2" align="center">
       <tr>
         <td>CASIO</td>
       </tr>
     </table>
       <table width="200" height="50" border="1" align="center"></table>
       <table width="200" border="1" align="center" bgcolor="gray" cellspaacing="30px">
   		<tr>
               <td>1</td>
               <td>2</td>
               <td>3</td>
               <td>+</td>
           </tr>
           <tr>
               <td>4</td>
               <td>5</td>
               <td>6</td>
               <td>-</td>
           </tr>
           <tr>
               <td>7</td>
               <td>8</td>
               <td>9</td>
               <td>*</td>
           </tr>
           <tr>
               <td>0</td>
               <td>=</td>
               <td>CE</td>

   <!DOCTYPE html>
   <html lang="en">
   <head>
       <meta charset="UTF-8">
       <title>登录界面</title>
   </head>
   <body>
   <form >
       <fieldset  style="width:300px;height:230px;margin:0 auto;">
           <legend align="center">登录界面</legend>
           <p align="center">用户名:<input type="text" maxlength="25"></p>
           <p align="center">密&nbsp;&nbsp;&nbsp;&nbsp;码:<input type="password" maxlength="25"></p>
           <p align="center">类型:<input type="radio" name="user">管理员 <input type="radio" name="user">普通用户</p>
           <p align="center"><input type="checkbox">记住密码 <input type="checkbox">自动登录</p>
           <p align="center"><input type="submit">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<input type="reset"></p>
