Can anyone guide me on locating the current CSS of my shiny app?

I am completely new to CSS so I may be asking the wrong question, but does using navbarPage mean I am incorporating CSS into my web app? I tried adding my own CSS to change some text and background colors...

    <STYLE TYPE='text/css'>
/* CSS created at csscreator.com */
BODY{background-color:#36454f; }
P{color:#999999; }
</STYLE>

...but then my Navbar disappeared and my tabs turned into simple hyperlinks below the main title. Can someone explain why this happened?

ui.R

    library(shiny)

shinyUI(navbarPage("main title", theme = "www/my_css.css",
  tabPanel("Dashboard",
          plotOutput("plot1",       width = "1600px"),
          plotOutput("plot2",       width = "1600px"),
          plotOutput("plot3", width = "1600px"),
          actionButton("refresh", "Refresh now")),
  tabPanel("About" , p("test"))
    )  
  )

Is there a way to view the CSS code that the app generates?

Is there a way to access the CSS of a Shiny app?

One method to access a Shiny app's CSS (specifically on Chrome Version 41.0.2272.101) is to right-click on the page and select the option "View page source." This will open a new tab displaying an HTML file corresponding to the Shiny app. Within this HTML file, you can find references to CSS files used in the app, such as:

<link href="shared/datepicker/css/datepicker.css" rel="stylesheet" />

By clicking on the "shared/..." path, you can view the CSS file being used by the app.
