Brilliant: how to adjust tabsetPanel width?

Here is my app built into my site. I want to get rid of the scroll widget below my application, this is due to the width of the tabsetPanel.

I am implementing the application using this code:

<iframe width="800" height="480" frameborder="0" src="http://spark.rstudio.com/alstated/meanvar/"></iframe>

Application Codes:

ui.R

library(shiny)

# Define UI for application that plots random distributions 
shinyUI(pageWithSidebar(
  headerPanel(title = ""),
  sidebarPanel(
    sliderInput("size",
                "Number of Observations",
                min = 10,
                max = 200,
                value = 95),

    sliderInput("mu",
                "Mean",
                min = -100, 
                max = 100,
                value = 0),

    sliderInput("sd",
                "Standard Deviation",
                min = 1,
                max = 6,
                value = 3),

    checkboxInput(inputId = "indiv_obs",
                  label = "Show individual observations",
                  value = FALSE),

    checkboxInput(inputId = "density",
                  label = "Show density estimate",
                  value = FALSE),

    conditionalPanel(condition = "input.density == true",
                     sliderInput(inputId = "bw_adjust",
                                 label = "Bandwidth Adjustment",
                                 min = 0.2,
                                 max = 2,
                                 value = 1,
                                 step = 0.2))
  ),
  mainPanel(
    tabsetPanel(
      tabPanel("Plot", 
               plotOutput(
                 outputId = "histogram", 
                 height = "400px",
                 width = "400px")),
      tabPanel("Summary",
               verbatimTextOutput(outputId = "datsummary"))
    ))
)
)

server.R

library(shiny)

# Define server logic required to generate and plot a random distribution
shinyServer(function(input, output) {

  data <- reactive(rnorm(
    n = input$size, 
    mean = input$mu, 
    sd = input$sd
  ))

  output$histogram <- renderPlot({

    hist(data(),
         probability = TRUE,
         xlab = "Data",
         ylab = "Density",
         main = "Histogram of Random Samples")

    if(input$indiv_obs){
      rug(data())
    }

    if(input$density){
      dens <- density(data(), adjust = input$bw_adjust)
      lines(dens, col = "blue")
    }

  })

  output$datsummary <- renderPrint(summary(data()))
})

Any help is much appreciated!

:

$(function (){

/* In addClass you can specify the class of the div that you want. In this example, 
I make use of a standard Bootstrap class to change the width of the tabset: col-sm-12. 
If you want the tabset to be smaller use: col-sm-11, col-sm-10, ... or add
and create your own class. */

Another way to adjust the width, sidebarPaneland tabsetPanelwas based on the change in the properties of widthCSS classes col-sm-4and col-sm-8respectively.
Using tag$headand tag$style, you can add CSS directly to the Brilliant interface.
See https://shiny.rstudio.com/articles/css.html for more details .
This is not an elegant solution, but it works correctly.

Brilliant interface

shinyUI(fluidPage(
  tags$head(
    tags$style(HTML("   
     .col-sm-4 { width: 25%;}
     .col-sm-8 { width: 75%;}
    "))
  ),       
  headerPanel(title = ""),
  sidebarPanel(
    sliderInput("size",
                "Number of Observations",
                min = 10,
                max = 200,
