我有一个图形布局和垂直滑块布局。我想把滑块放在网格上，这样我就可以沿y轴移动。如何在破折号代码中嵌入css。有人能指引我吗？

import dash
from dash.dependencies import Input, Output, State
import dash_core_components as dcc
import dash_html_components as html
import plotly

app = dash.Dash()

app.layout = html.Div([
    dcc.Slider(
        id='my-slider',
        updatemode = "drag",
        vertical = True,
        min=10,
        max=40,
        step=10,
        value=10,
    ),
    html.Div(id='slider-output-container'),

    html.Div([
          dcc.Graph(id="plot_1"),

])

])

If someone replies it will be more helpful for me to develop.

Thanks,
Meera
