Background color of tabs in shiny tabPanel

The above example is broken apparently (from version 0.14.0), probably due to a Shiny css change. Additionally the title of the post promises more than the actual question and solution actually covered. So I wrote a new more comprehensive example.

  • It sets the default tab background to be aqua and black text.
  • It sets the color of several tabs to be explicit colors (when they are not active) with white text.
  • It sets the active tab background to be black with white text.

Whether or not all these colors are a good idea from a UI point of view is another question…

Here is the code:

library(shiny)
ui <-shinyUI(fluidPage(
  h1("Colored Tabs"),
  tags$style(HTML("
    .tabbable > .nav > li > a                  {background-color: aqua;  color:black}
    .tabbable > .nav > li > a[data-value="t1"] {background-color: red;   color:white}
    .tabbable > .nav > li > a[data-value="t2"] {background-color: blue;  color:white}
    .tabbable > .nav > li > a[data-value="t3"] {background-color: green; color:white}
    .tabbable > .nav > li[class=active]    > a {background-color: black; color:white}
  ")),
  tabsetPanel(
    tabPanel("t0",h2("normal tab")),
    tabPanel("t1",h2("red tab")),
    tabPanel("t2",h2("blue tab")), 
    tabPanel("t3",h2("green tab")),
    tabPanel("t4",h2("normal tab")),
    tabPanel("t5",h2("normal tab"))
  )
))
server <- function(input, output) {}
shinyApp(ui=ui,server=server)

Here is a screen shot:

And in case this breaks again, and the code has to be adjusted, here is the current css/html that is producing this:

<body>
  <div class="container-fluid">
    <h1>Colored Tabs</h1>
    <style>
    .tabbable > .nav > li > a                  {background-color: aqua;  color:black}
    .tabbable > .nav > li > a[data-value="t1"] {background-color: red;   color:white}
    .tabbable > .nav > li > a[data-value="t2"] {background-color: blue;  color:white}
    .tabbable > .nav > li > a[data-value="t3"] {background-color: green; color:white}
    .tabbable > .nav > li[class=active]    > a {background-color: black; color:white}
  </style>
    <div class="tabbable">
      <ul class="nav nav-tabs">
        <li class="active">
          <a href="#tab-5851-1" data-toggle="tab" data-value="t0">t0</a>
