应用程序不拾取.css文件（flask / python） [英] Application not picking up .css file (flask/python)
问题描述
我正在渲染一个模板，我试图用外部样式表来样式。文件结构如下。
I am rendering a template, that I am attempting to style with an external style sheet. File structure is as follows.
/app
- app_runner.py
/services
- app.py
/templates
- mainpage.html
/styles
- mainpage.css
mainpage.html看起来像这样
mainpage.html looks like this
<html>
<head>
<link rel= "stylesheet" type= "text/css" href= "../styles/mainpage.css">
</head>
<body>
<!-- content -->
我的样式都没有应用。它有什么与事实，html是我渲染的模板吗？
None of my styles are being applied though. Does it have something to do with the fact that the html is a template I am rendering? The python looks like this.
return render_template("mainpage.html", variables..)
我知道这很多工作，因为我仍然能够渲染模板。然而，当我试图将我的样式代码从html的head标签中的样式块移动到外部文件时，所有的样式都消失了，留下一个裸html页面。任何人都看到我的文件结构的任何错误？
I know this much is working, because I am still able to render the template. However, when I tried to move my styling code from a "style" block within the html's "head" tag to an external file, all the styling went away, leaving a bare html page. Anyone see any errors with my file structure?
推荐答案
您需要有一个静态文件夹设置），除非你在Flask初始化期间专门覆盖它。我假设你没有重写它。
You need to have a 'static' folder setup (for css/js files) unless you specifically override it during Flask initialization. I am assuming you did not override it.
您的css的目录结构应如下所示：
Your directory structure for css should be like:
/app
- app_runner.py
/services
- app.py
/templates
- mainpage.html
/static
/styles
- mainpage.css
注意你的/ styles目录应该在/ static
Notice that your /styles directory should be under /static
然后，执行此操作
<link rel= "stylesheet" type= "text/css" href= "{{ url_for('static',filename='styles/mainpage.css') }}">
Flask现在将在static / styles / mainpage.css
Flask will now look for the css file under static/styles/mainpage.css
