Question

这是我的新PHP

    <?php

    /**
    * Make sure you started your'e sessions!
    * You need to include su.inc.php to make SimpleUsers Work
    * After that, create an instance of SimpleUsers and your'e all set!
    */

    session_start();
    require_once(dirname(__FILE__)."/simpleusers/su.inc.php");

    $SimpleUsers = new SimpleUsers();

    // Login from post data
    if( isset($_POST["username"]) )
    {

        // Attempt to login the user - if credentials are valid, it returns the users id, otherwise (bool)false.
        $res = $SimpleUsers->loginUser($_POST["username"], $_POST["password"]);
        if(!$res)
            $error = "You supplied the wrong credentials.";
        else
        {
                header("Location: users.php");
                exit;
        }

    } // Validation end

echo '<link href="css/style.css" rel="stylesheet">';

输入框（密码，用户名）不是CSS的主题，它们只是默认的。相同的代码（减去PHP）在HTML中运行良好，任何关于导致CSS在PHP中无效的想法？我已经检查了一些其他问题并重新格式化了代码2次。一旦我开始工作，我将如何使用CSS中心登录框？

编辑：现在只有用户名框不是主题 - 检查我所做的更改。

谢谢！

Answer 1

你的头部元素非常凌乱。将其粘贴到它的位置，让我知道是否可以修复任何内容。

<head>
    <title></title>
    <meta http-equiv="content-type" content="text/html; charset=UTF-8" />
    <link rel="stylesheet" type="text/css" href="css/style.css" />
    <style type="text/css">

    h1
    {
        color: #000000;
        border-bottom: 2px solid #000000;
        margin-bottom: 15px;
    }

    p { margin: 10px 0px; }
    p.faded { color: #A0A0A0; }
  </style>
</head>

你的标签内部正在调用你的style.css。

Answer 2

<link rel="stylesheet" type="text/css" href="css/style.css />您忘记了"，并且您在css的第一个input中输了一个拼写错误。

Answer 3

你有点混淆了。 link 标记用于外部css文件。样式适用于直接css代码。将链接标记放在样式中甚至不是有效的HTML。简单地忽略链接。只是把链接放在风格之外。鉴于css的路径是正确的，一切都应该起作用。此外，内部样式无效。

Answer 4

<link rel="stylesheet" type="text/css" href="css/style.css" /> 

<style type="text/css">

        h1
        {
            color: #000000;
            border-bottom: 2px solid #000000;
            margin-bottom: 15px;
        }

        p { margin: 10px 0px; }
        p.faded { color: #A0A0A0; }

</style>

我认为这样会更好

CSS无法在我的页面上工作
