调整 UI shindashboardPlus 中的元素位置 header

Adjust UI element positions in shindashboardPlus header

我有一个闪亮的应用程序,在 Header 上有一个切换开关。按下切换按钮时,它会运行一个长函数,并向用户显示一条消息,表明正在发生某些事情。下面是一个非常简化的版本。

我拥有的功能很好,但 UI 未对齐。 header 上显示的开关和消息略高于左侧的最小化按钮(汉堡包)。我希望能够将开关和消息向下移动一点,以便它们与最小化按钮水平对齐,但我无法在 CSS 或各种 shiny/shinydashboard/shinydashboardPlus 函数。

此外,输出消息(和 htmlOutput 元素)在切换开关的右侧间隔很远,我想缩小切换开关和消息之间的间隙。

# Define UI for application that draws a histogram
ui <- dashboardPage(skin = 'blue', 
                    
shinydashboardPlus::dashboardHeader(title = 'Example',
    leftUi = tagList(
        useShinyjs(),
        switchInput(inputId = 'swtLabels', label = 'Labels', value = TRUE,
                    onLabel = 'Label 1', offLabel = 'Label 2',
                    onStatus = 'info', offStatus = 'info', size = 'mini', 
                    handleWidth = 230),
        htmlOutput(outputId = 'labelMessage')
        )
    ),
    dashboardSidebar(),
    dashboardBody()
)

server <- function(input, output) {  
  observeEvent(input$swtLabels, {
     shinyjs::html(id = 'labelMessage', html = 'Starting...')
     shinyjs::showElement(id = 'labelMessage')
     Sys.sleep(1)
     shinyjs::html(id = 'labelMessage', html = 'Done') 
     shinyjs::hideElement(id = 'labelMessage', anim = TRUE, animType = 'fade', time = 2.0) 
  })
}

shinyApp(ui = ui, server = server)

尝试margin-top: 6px。见下文。
