【中文标题】如何让 CSS 文件正确应用于我的 PHP/HTML 代码?【英文标题】:How do I get the CSS file to apply correctly to my PHP/HTML code? 【发布时间】:2018-11-29 01:36:18 【问题描述】:看起来像这样:
但它应该看起来像video at 26:05。
有几件事我想问:
如果我想将代码链接到数据库,代码是否仍然有效? 如果我要更改一些 CSS,它会起作用吗? 错误是在 CSS 中还是在 html 文件中?它应该在页面的右侧。

【问题讨论】:
显示你的文件夹结构 使用指向外部网站(youtube 等)的链接意味着,随着时间的推移,即使这个问题得到了正确且对您有用的答案,随着时间的推移,它也会变得毫无用处,因为外部链接将变得无效。请尝试为您的问题制作一个完整的小例子。 看起来像一个 CSS 问题,我建议通过示例视频来捕捉缺失的样式。好的,这里有一些修复:
您在 html 中拼错了“class”(并且您不需要</link>
关闭);
有些类是在css上声明的,但是在html中没有使用(html:<form class="signup-form">
/css:.signup-form
);
您忘记添加视频告诉您的一些 CSS 属性(浮动:左);
我做了一些调整,但你应该尝试修复其余的:

说实话,我并没有完全理解你的问题,但我还是会尽力回答:
-
我没有看到与数据库链接的问题,因为您的代码中没有任何与数据库相关的内容...
CSS 主要是视觉效果,因此如果您更改它,它不会改变代码的功能。
在这种情况下,错误出现在 CSS 和 HTML 中。
不管怎样,希望对你有帮助。
【讨论】:
非常感谢你花了好几个小时试图找出 css 出了什么问题,并且非常关注它,以至于我什至没有意识到 html 中可能存在错误,我一直在代码学院学习如何编写 css 并认为我会尝试一下,我也确实查看了 html,但错误是如此基本,我跳过它而没有注意到,因为谁拼错了类。【参考方案2】:在我说什么之前,它是<link rel="stylesheet" href="style.css">
而不是<link rel="stylesheet" type="text/css" href="style.css"></link>
。你已经关闭了标签。这可能就是它不起作用的原因。无论如何,这是另一个解决方案。
我发现 this answer on *** 可以解决您的问题:
你必须用标签包围 CSS:
<?php include 'header.php'; ?>
<style>
<?php include 'CSS/main.css'; ?>
</style>
...PHP 包含以 .css 结尾也可以正常工作。通过这种方式,您甚至可以在 CSS 文件中使用 PHP。这对组织例如非常有帮助。颜色作为变量。
