No need for shinyjs

library(shinydashboard)
library(shiny)

ui <- dashboardPage(dashboardHeader(title = div('want to be red', style = "color: red;")),
                dashboardSidebar(),
                dashboardBody(),
                title = 'nhanesR')

server <- function(input, output, session) {}

shinyApp(ui, server)
