PHP開發簡單圖書後台管理系統管理員登入頁
這節來實作一個登陸頁面
建立一個<form>表單來實現登入頁面，如圖透過一堆小圖示組合出來的登入頁面。朋友們有興趣可以自己製作一些小圖示或比較酷炫的圖片載入到文件中使用，讓自己的登入頁顯得更加的高大上。
<body> <div id="top"> </div> <form id="frm" name="frm" method="post" action="" onSubmit="return check()"> <div id="center"> <div id="center_left"></div> <div id="center_middle"> <div class="user"> <label>用户名： <input type="text" name="username" id="username" /> </label> </div> <div class="user"> <label>密 码： <input type="password" name="pwd" id="pwd" /> </label> </div> <div class="chknumber"> <label>验证码： <input name="code" type="text" id="code" maxlength="4" class="chknumber_input" /> </label> <img src="verify.php" style="vertical-align:middle" /> </div> </div> <div id="center_middle_right"></div> <div id="center_submit"> <div class="button"> <input type="submit" name="Submit" class="submit" value=" "> </div> <div class="button"><input type="reset" name="Submit" class="reset" value=""> </div> </div> </div> </form> <div id="footer"></div> </body>
把CSS樣式打包建立一個style.css檔案
<link rel="stylesheet" type="text/css" href="style.css"/>
在<head>中加入上面的link，呼叫css檔案。
