python - Flask Templates couldn't load css -

i followed tutorial develop templates flask http://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-ii-templates

my file tree next one:

/static    /js         bootstrap.min.js         jquery_1.11.3.js    /css         bootstrap.min.css    /images /templates         index.html /python_venv server.py 

server.py code:

     @app.route('/subdomain/')      def getprevisionpoblacion():           return render_template('index.html') 

and css link inside index.html code following:

      <script src="/static/js/bootstrap.min.js"></script>       <link rel="stylesheet" href="/static/css/bootstrap.min.css"/>       <script src="/static/js/jquery_1.11.3.js"></script> 

nginx config:

      location /subdomain/{       root        /apps/subdomain/static;       uwsgi_pass  unix:///tmp/subdomain.sock;       include     uwsgi_params;       } 

when check on chrome, index didn't load css files. checked network developer's tools , error 404. tried similar code saw on unresolved question without success inline css background:url() not working in jinja2 template

any ?

the problem server.

i had serve static folder flask template can load css.

i wrote in nginx config file next:

    location /subdomain/static)/  {        root    /opt/apps/content_folder/static;     } 

i don't use url_for() function y wrote resource's url as:

    static/css/my_css_template.css 

finally check out @app.route() inside file render template correct flask template access css, images , js.
