Problems with Dash bootstrap

I’m new to dash bootstrap, but it seems interesting. The problem that I have is fitting two pieces of the puzzle together. If I use their simple sidebar program to set up my website, I don’t seem to be able to call any of the code snippets that they show in their website.

My question is how do I get the two pieces to fit together?

Code for the simple sidebar:

Code for the simple example of forms:

import dash_bootstrap_components as dbc

email_input = dbc.FormGroup(
    [
        dbc.Label("Email", html_for="example-email"),
        dbc.Input(type="email", id="example-email", placeholder="Enter email"),
        dbc.FormText(
            "Are you on email? You simply have to be these days",
            color="secondary",
        ),
    ]
)

password_input = dbc.FormGroup(
    [
        dbc.Label("Password", html_for="example-password"),
        dbc.Input(
            type="password",
            id="example-password",
            placeholder="Enter password",
        ),
        dbc.FormText(
            "A password stops mean people taking your stuff", color="secondary"
        ),
    ]
)

form = dbc.Form([email_input, password_input])
