Python Flask页面不使用外部CSS和Javascrip呈现

Question

我创建了一个Python Flask应用程序，其中一个HTML文件中包含HTML/CSS/Javascript。这很好。在

我想把CSS和Javascript文件分成他们自己的文件。我这样做了，并修改了HTML文件，以适应CSS和Javascript文件的新位置。在

但是页面不会呈现。当我打开一个“找不到”错误页面时。在

我想将CSS和Javascript分开，这样我就可以在不需要管理HMTL和CSS的情况下使用Javascript。任何帮助都将不胜感激。在

以下是工作的原始HTML文件：

{% extends "base.html" %}

{% block title %}test.com{% endblock %}

{% block page_content %}

下面是一些新代码，但它并不像我预期的那样工作：

^{pr2}$

Answer 1

关闭rel、type和href后等号后面的空格。在

<link rel= "stylesheet" type= "text/css" href= "{{ url_for('static',filename='styles/style.css') }}">

到

^{pr2}$

看来这就是罪魁祸首。在
