如何在Shiny中调整条件面板的位置？

我正在尝试调整条件面板的位置。现在，条件面板固定在浏览器的左边缘，我想将其稍微向右移动。我可以知道该怎么做吗？以下是我闪亮的应用程序的简化虚拟版。

用户界面

library(shiny)
library(dygraphs)

shinyUI(fluidPage(
    titlePanel(p("Indicators (Dummy Ver.)"), 
        windowTitle = "Indicators"),

    sidebarLayout(
        conditionalPanel(condition="input.conditionedPanels==2",
            tags$style(type="text/css", '#leftPanel { width:250px; float:left;}'),
            id = "leftPanel",
            radioButtons("timeInterval", label = h3("Time Interval"),
                    choices = c("Hourly","Daily"),
                    selected = "Hourly")
            ),
        mainPanel(
            tabsetPanel(
                tabPanel("SNES", value=1,
                    dygraphOutput("tsPlot1"),
                    h3("Header"),
                    p("Descriptions")
                ),
                tabPanel("MA", value=2,
                    dygraphOutput("tsPlot2"),
                    h3("Header"),
                    p("Descriptions")               
                ),
                id = "conditionedPanels"
            )
        )    
    )
))

服务器

library(shiny)
library(dygraphs)
library(xts)

x1 <- arima.sim(model=list(ar=c(.9,-.2)),n=100)
x2 <- arima.sim(model=list(ar=c(0.8,0.1)),n=100)

start <- as.POSIXct("2015-08-01 08:00")
interval <- 60
end <- start + as.difftime(99, units="hours")
timeSeq <- seq(from=start, by=interval*60, to=end)


shinyServer(
    function(input, output){

        SNES <- xts(x1, order.by = timeSeq)
        names(SNES) <- c("Sentiment")

        marine <- xts(x2, order.by = timeSeq)
        names(SNES) <- c("Activities")

        output$tsPlot1 <- renderDygraph({
            dygraph(SNES,main="Sentiment",
                ylab="Frequency") %>%
                dyLegend(width = 760)  %>% 
                dyRangeSelector(height = 20)
        })

        output$tsPlot2 <- renderDygraph({
            dygraph(marine,main="Arrivals & Departures",
                ylab="Frequency") %>%
                dyLegend(width = 720)  %>% 
                dyRangeSelector(height = 20)
        })

    }
)
