永久更改闪亮仪表板中的标题页眉颜色

我有下面闪亮的仪表板，我需要永久更改包含标题的标题的颜色。现在，当我将鼠标悬停在上面时，它会返回到以前的颜色。

library(DT)
ui <- dashboardPage(
    dashboardHeader(title = "Dynamic sidebar"),
    dashboardSidebar(
        width=400
    ),
    dashboardBody(
        tags$head(tags$style(HTML('

        /* logo */
        .skin-blue .main-header .logo {
                              background-color: #E7FF6E;
                              }'))) 
    )
)

server <- function(input, output) {



}

shinyApp(ui, server)

解决方案

您可以使用{Fresh}包创建与{shinydashboard}一起使用的自定义主题，更多文档请点击此处：https://dreamrs.github.io/fresh/articles/vars-shinydashboard.html

以下是修改页眉背景颜色的示例：

library(fresh)
# Create the theme
mytheme <- create_theme(
  adminlte_color(
    light_blue = "#E7FF6E"
  )
)


library(shiny)
library(shinydashboard)

ui <- dashboardPage(
  header = dashboardHeader(title = "My dashboard"),
  sidebar = dashboardSidebar(
    sidebarMenu(
      menuItem("Dashboard", tabName = "dashboard", icon = icon("dashboard")),
      menuItem("Settings", tabName = "settings", icon = icon("sliders"))
    )
  ),
  body = dashboardBody(

    use_theme(mytheme) # <-- use the theme
  )
)

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

}

shinyApp(ui, server)
