How would you get your template to use a specific css file in Flask?

admin.html = admin.css  
user.html = user.css

I’ve looked at the Flask docs and they don’t make sense?

    You can overwrite the <head> section in your base template in a child template. So every user page use the css file from the base.html template and only the admin.html use the other file. This is documented in http://flask.pocoo.org/docs/patterns/templateinheritance/#template-inheritance

    Edit:
    Maybe you can use this: All pages derive from base.html and use base.css. Only user.html and admin.html overwrite the head section and include base.css and the specific admin.css / user.css.

    Example :

    base.html: 

         <!doctype html>
     <html>
     <head>
      {% block head %}
        <link rel="stylesheet" href="{{ url_for('static', filename='base.css') }}">
      {% endblock %}
      </head>
      <body>
      <div id="content">{% block content %}{% endblock %}</div>

     </body>
     </html>

    admin.html:

        {% extends "base.html" %}
    {% block head %}
      <link rel="stylesheet" href="{{ url_for('static', filename='base.css') }}">
      <link rel="stylesheet" href="{{ url_for('static', filename='admin.css') }}">
    {% endblock %}
    {% block content %}
     content goes here
    {% endblock %}

    user.html:

        {% extends "base.html" %}
    {% block head %}
      <link rel="stylesheet" href="{{ url_for('static', filename='base.css') }}">
      <link rel="stylesheet" href="{{ url_for('static', filename='user.css') }}">
    {% endblock %}
    {% block content %}
     content goes here
    {% endblock %}

    Edit:
    If you store your css files in a sub directory of static/ you must write the link like this:

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