更改 shinydashboard 特定部分的背景颜色 body

Question

我在下面有 .rmd 文件，我通过 shiny 应用程序显示它。我想将包含在这 6 列 space 中的整个 space 的背景颜色更改为白色，而不仅仅是标题。我怎样才能做到这一点？其余 6 列（左 3 列，右 3 列）应保持相同的颜色。

app.r

library(shiny)
library(shinydashboard)
library(shinydashboardPlus)
library(shinyjs)
library(knitr)
library(rmarkdown)

dbHeader <- dashboardHeaderPlus(disable = TRUE
                                
                                
)
shinyApp(
  ui = dashboardPagePlus(
    header = dbHeader,
    sidebar = dashboardSidebar(width = "0px",
                               sidebarMenu(id = "sidebar" # id important for updateTabItems
                                           
                               )          ),
    body = dashboardBody(
      tags$head(tags$style(HTML('
  h1{
  font-size: 12pt;
  font-family: "Montserrat Light", sans-serif;
  text-align: justify;
  background-color: white;
}
  H1.title{
  font-size: 44pt;
  font-family: "Chronicle Display Light", Times, serif;
  text-align: right;
  background-color: white;
}
  H1{
  font-size: 44pt;
  font-family: "Chronicle Display Light", Times, serif;
  text-align: right;
  background-color: white;
}
  H2{
  font-size: 16pt;
  font-weight: bold;
  font-family: "Chronicle Display Light", Times, serif;
  text-align: left;
  background-color: white;
}
    '))),
      
      useShinyjs(),
      tags$script(HTML("$('body').addClass('fixed');")),
      fluidRow(
        column(3,),
        column(6,
      uiOutput("info")))
      
      
      
    )
    
  ),
  server<-shinyServer(function(input, output,session) { 
    hide(selector = "body > div > header > nav > a")
    
    
    output$info <- renderUI({
      
      isolate(HTML(markdown::markdownToHTML(knit('Information2.rmd', quiet = TRUE),fragment.only=TRUE)))
      
    })
    
    
  }
  )
)

Information2.rmd

output:
  html_document: default

这可以通过添加 CSS 规则来实现

#info {
    background-color: white;
}

info 是 div 标签的 id 包含你的 Rmd 的内容。
