Aligning buttons in Dash

Question

I want to align the my buttons - 'left_button' and 'right_button' so it fits on the edges of each of the right left most corner of the images and right most corner of the images.

right now it looks like this image of buttons not correctly in positions

Here is the code for the layouts

any tips would be great. Thanks

layout = dbc.Container(
    [
        html.Div(
            [
                dbc.Row(
                    dbc.Col(
                        navbar,
                    ),
                ),
                dbc.Row(
                    [
                        dbc.Col(headwear, width=3),
                        dbc.Col(topwear, width=3),
                    ],
                    justify="center",
                    className="mt-3",
                ),
                dbc.Row(
                    [
                        dbc.Col(bottomwear, width=3),
                        dbc.Col(footwear, width=3),
                    ],
