How to increase my container width to accomodate more items - plotly-dash

Question

I am building a dashboard using Plotly Dash. I am using bootstrap.min.css , I would like to increase the width of my container so that I can accommodate two graphs , in a single row.
My second graphs(Line graph) , has more width hence unable to align them in a single row.
I have attached the snapshot below,
DASH UI CODE :
# the style arguments for the sidebar. We use position:fixed and a fixed width
SIDEBAR_STYLE = {
"top": 0,
"left": 0,
"bottom": 0,
"width": "16rem",
"padding": "2rem 1rem",
"background-color": "#f8f9fa",
"position": "fixed",
"color":"#000",
}
# the styles for the main content position it to the right of the sidebar and
# add some padding.
CONTENT_STYLE = {
"margin-left": "18rem",
"margin-right": "2rem",
"padding": "2rem 1rem",
}
sidebar = html.Div(
[
html.H2("Plate", className="display-4"),
html.Hr(),
html.P(
"A simple dashboard", className="lead"
),
dbc.Nav(
[
dbc.NavLink("Dashboard", href="/dashboard", id="page-1-link"),
dbc.NavLink("Analytics", href="/page-2", id="page-2-link"),
dbc.NavLink("Page 3", href="/page-3", id="page-3-link"),
html.Hr(),
dbc.NavLink("Logout", href="/logout", id="page-4-link"),
],
vertical=True,
pills=True,
),
],
style=SIDEBAR_STYLE,
)
content = html.Div(id='page-content' , className ='container' ,style=CONTENT_STYLE)
app.layout = html.Div([dcc.Location(id="url"), sidebar, content])
app.config.suppress_callback_exceptions = True
# this callback uses the current pathname to set the active state of the
# corresponding nav link to true, allowing users to tell see page they are on
#app.callback(
[Output(f"page-{i}-link", "active") for i in range(1, 4)],
[Input("url", "pathname")],
)
def toggle_active_links(pathname):
if pathname == "/" or pathname == "/dashboard":
# Treat page 1 as the homepage / index
return True, False, False
return [pathname == f"/page-{i}" for i in range(1, 4)]
#app.callback(Output("page-content", "children"), [Input("url", "pathname")])
def render_page_content(pathname):
if pathname in ["/", "/page-1", "/dashboard"]:
dashBoard = html.Div([
html.Div([dcc.DatePickerRange(

html.Div([

], className = 'col'),
html.Div([dcc.Graph(id='categoryPerformanceTrend')
], className = 'col')
], className = 'row'),
html.Hr(),
html.Div([

], className = 'col-6 col-md-4'),
html.Div([

])
] , className='container')
return dashBoard
