Thanks a lot @adamschroeder for your reply.
I tried the code below but I still don’t get them on the same line and they are left aligned.
app.layout = html.Div(children=
[
dbc.Container(children=[
dbc.Row([
dbc.Col(html.H1(children=['Tweet Performance Dashboard']), width=8),
dbc.Col(html.Img(src="path/logo.png"), width=4)
], justify='start')
])
])
Do you have any idea what I am doing wrong here?
