Enhance Your R Shiny App: Give SidebarPanel and MainPanel a Sleek Black Border

Is there a way to enhance the appearance of the main panel and sidebar panel for the MRE by adding a black border? I want these panels to have more visual impact, even though I've already adjusted the background color on my app. Adding a black border may help each panel stand out more effectively.

UI

library(shiny)
library(shinyalert)

# Define UI for application that draws a histogram
shinyUI(fluidPage(

    # Application title
    titlePanel("Old Faithful Geyser Data"),

    # Sidebar with a slider input for number of bins
    sidebarLayout(
        sidebarPanel(
            
        ),

        # Show a plot of the generated distribution
        mainPanel(
          DT::dataTableOutput("cap_table"),
        
        )
    )
))


Server

library(shiny)
library(shinyalert)

data <- data.frame(x=rnorm(10),y=rnorm(10))

# Define server logic required to draw a histogram
shinyServer(function(input, output) {


  
  # render data selection
  output$cap_table <- DT::renderDataTable(data)

    

})

Answer №1

To enhance the appearance of your app, you might want to consider incorporating custom CSS. One way to do this is by right-clicking on the running app and selecting "inspect" to identify the CSS class that needs modification.

For example, here is how you can use in-line code:

If you are looking for alternative approaches, you can explore using an external CSS file. Check out this link for more information:

library(shiny)
library(DT)

# Define UI for application generating a histogram
ui <- shinyUI(
  fluidPage(
  tags$head(
    # Wrap string in HTML()
    tags$style(HTML(".well {
        border: 1px solid #000000;
      }")), 
    tags$style(HTML(".col-sm-8 {
        border: 1px solid #000000;
      }"))
  ),
  # Application title
  titlePanel("Old Faithful Geyser Data"),
  
  # Sidebar with slider input for number of bins
  sidebarLayout(
    sidebarPanel(
      
    ),
    
    # Display plot of generated distribution
    mainPanel(
      DT::dataTableOutput("cap_table"),
      
    )
  )
))


data <- data.frame(x=rnorm(10),y=rnorm(10))

# Define server logic for drawing histogram
server <- shinyServer(function(input, output) {
  
  
  
  # render data selection
  output$cap_table <- DT::renderDataTable(data)
  
})

shinyApp(ui = ui, server = server)
