  dash-bootstrap-components provides Bootstrap components.
  
  Plotly Dash is great! However, creating the initial layout can require a lot 
  of boilerplate. dash-bootstrap-components reduces this boilerplate by providing 
  standard layouts and high-level components.
  
  A good way to start customising the stylesheet is to use an alternative 
  pre-compiled theme. Bootswatch is a great place to find new themes. Links to 
  CDNs for each of the Bootswatch styles are also included , and can be used 
  with the external_stylesheets argument of the Dash constructor:
  
  app = dash.Dash(__name__, external_stylesheets=[dbc.themes.CERULEAN])
  
  Go to https://bootswatch.com/ to preview these Bootswatch themes:
  
  dbc.themes.BOOTSTRAP

  dbc.themes.COSMO
  dbc.themes.CYBORG
