Change the color and font of text in Shiny App

fonts, r, shiny, styles

Solution

You can use css as @jbaums indicated

library(shiny)
runApp(list(
  ui = bootstrapPage(
    numericInput('n', 'Number of obs', 100),
    textOutput('text1'),
    tags$head(tags$style("#text1{color: red;
                                 font-size: 20px;
                                 font-style: italic;
                                 }"
                         )
              )
  ),
  server = function(input, output) {
    output$text1 <- renderText({ paste("hello input is",input$n) })
  }
))

Normally you would include this in a `styles.css` file but it is shown inline here to be self contained. `#text1` refers to the DOM element with `id=text1` and the contents of the curly brackets are the relevant styles.

Problem

I am using below code in `server.R` to display the text in the main panel. This is working exactly the way it should work. ``` output$text1 <- renderText({ if(input$ag == 0) return(NULL) return('First 20 rows for requested AG') }) ``` Is there any way to change the font and color of the text?
