title: Change font family throughout entire R Shiny App: CSS/HTML
body: <p>Is it possible to change the default font of an entire shiny dashboard app? Including font for the sidebar, body, header, ggplots within the app, etc?</p>
  
  <p>I know you can add font-family statements within each piece
  ( example: h2(strong(textOutput("t")), style = "font-family: 'Arial';")),
   but I want my entire app to use Arial and I don't want to have to write a line of code for every single feature. Is there a short cut?</p>
  
  <p>Also, inline CSS is preferred to a separate css file if possible.</p>
  
  <p>Thanks,
  Sarah</p>
  
  <p><strong>Edit:</strong> </p>
  
  <p><strong>Here is some of my code. Could you show me where I would put the necessary CSS?</strong> </p>
  
  <pre><code>body&lt;-dashboardBody( tags$style(".content {background-color: black;}"),
                   useShinyjs(),
                   tags$style(type='text/css', ".skin-blue .main-header .logo {background-color: #000000}" ),
                   tags$style(type='text/css', ".skin-blue .main-header .logo:hover {background-color: #000000}"),
                   tags$style(type='text/css', ".skin-blue .main-header .navbar {background-color: #000000}"),
                   tags$style(type="text/css",".shiny-output-error { visibility: hidden; }",".shiny-output-error:before { visibility: hidden; }"),
                   fluidPage(
                     img(src="img2.PNG",height="100%", width="100%",style='padding:0px;'),
                     br(),br(),
                     tabBox("Menu Database", width = 12,
                            tabPanel("Menu Database", 
                                     tabsetPanel(
                                       tabPanel("LTO Survey results",
