标头css / bootstrap问题，很奇怪
[英]Headers css/bootstrap issues, strange
问题描述
I do not understand what is going on here. 
我不明白这是怎么回事。
This is my file-data "structure": 这是我的文件数据“结构”：
Over here is the content of my folder "css" 这是我的文件夹“ css”的内容
So, in my program: this files"estudiante.php","editar.php" and "hola.php" got the same header. 因此，在我的程序中：该文件“ estudiante.php”，“ editar.php”和“ hola.php”具有相同的头。 Take a look: 看一看：
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<script src="http://code.jquery.com/jquery-2.1.1.min.js"></script>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js" integrity="sha384-Tc5IQib027qvyjSMfHjOMaLkfuWVxZxUPnCJA7l2mCWNIpG9mGCD8wGNIcPD7Txa" crossorigin="anonymous"></script>
</head>
The problem is that i could not link the file "estilos.css" from the "css" folder because i was given some errors while i was checking the inspect element tool using chrome: 问题是我无法从“ css”文件夹链接文件“ estilos.css”，因为在使用chrome检查检查元素工具时出现了一些错误：
But it is strange, because i wrote this line on my header: 但这很奇怪，因为我在标头上写了这一行：
<meta name="viewport" content="width=device-width, initial-scale=1">
That line makes my page responsive, but those commands are in my estilos.css file.. i don get it, take a look: 那行使我的页面响应，但是这些命令在我的estilos.css文件中。我不明白，看一下：
So, estilos.css doesnt appear in my code but the header uses the content and makes my website responsive?. 因此，estilos.css没有出现在我的代码中，但是标题使用了内容并使我的网站具有响应能力？ I dont understand this mates :( 我不明白这个队友:(

Double-check your file naming conventions. 仔细检查您的文件命名约定。 It looks like you're hiding file extensions, since bootstrap , bootstrap.min , etc don't have .css on the end, but estilos.css does. 看来您正在隐藏文件扩展名，因为bootstrap ， bootstrap.min等结尾没有.css ，而estilos.css 。 It's possible your file is actually named estilos.css.css and you aren't aware. 您的文件实际上可能名为estilos.css.css ，但您可能不知道。
