title: How to change the background color of the Shiny Dashboard Body
body: <p>I cannot get the scope to change the background color of the shiny dashboard's body. I do not want to use outside CSS because it is not supported in the Shiny server which I'm hosting. Whatever I do I'm unable to find the HTML tag for the dashboard's background so I could change it. The background color is always <code>#ECF0F5</code> whatever I do. Here is a reproducible application.</p>
  
  <pre><code>library(shinydashboard)
  library(shiny)
  library(DT)
  library(shinyWidgets)
  library(dplyr)
  ui=shinyUI(
    dashboardPage(
      dashboardHeader(
        title = "Example of a long title that needs more space",
        titleWidth = 450
      ),
      dashboardSidebar( sidebarMenu(
        menuItem("Dashboard", tabName = "dashboard", icon = icon("dashboard")),
        menuItem("Widgets", icon = icon("th"), tabName = "widgets",
                 badgeLabel = "new", badgeColor = "green")
      )),
      dashboardBody(
        # Also add some custom CSS to make the title background area the same
        # color as the rest of the header.
