title: R Shiny: How do you change the background color of the Header?
body: <p>I am writing a shiny application and I would like to customize the look of the header. I am able to add images and format the text, but what I would like to do is change the background color, but only for the header panel, not the rest of the ui.  So far I have this for my </p>
  
  <pre><code>ui.r:
  
  shinyUI(pageWithSidebar(
  
  headerPanel(
  list(tags$head(tags$style("body {background-color: black; }")),
  "Graphs", HTML('&lt;img src="ah_large_black.gif", height="200px"    
  style="float:right"/&gt;','&lt;p style="color:red"&gt; test test &lt;/p&gt;' ))
  ),
  </code></pre>
  
  <p>This has text of two different colors and puts an image on the right side, but it make the background color of everything black. Is there a way to limit the color this to just the header?</p>
