Answer 1

Tried almost every solution on Stack Overflow. It only worked for me when I placed the static folder in the same directory as my run.py file. I changed my folder structure from:

app/
    views
    static
    templates
run.py

To:

app/
    views
    templates
static
run.py

I guess moving the run.py instead would work too. Have a look at this Jinja Templating Tutorial for extra info. Not sure why I had to change the structure for it to work though.

Answer 2

To add to what's been said here, be sure to update Jinja2 to v2.10, as lesser versions seem to cause this same bug. Cheers!

Answer 3

The order of handler might cause the problems:

url: /stylesheets static_dir: stylesheets
url: /.* script: helloworld.application

will work instead of

url: /.* script: helloworld.application
url: /stylesheets static_dir: stylesheets

Answer 4

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

href value must be within quotes.

make sure the file name and path are proper OR try the below

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

Answer 5

All public files (the ones that are not processed, like templates or python files) should be placed into dedicated static folders. By default, Jinja2 has one static folder called static.

This should fix your problem:

1. Move /templates/styles.css to /static/styles.css

2. Update your code with following code, that will be translated into correct file location:

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