如何更改 Shinymanager 登录页面的颜色?
How to change the color of the Shinymanager Login Page?
我正在尝试更改 shinymanager
包中登录页面的色调。
我看过这些帖子:
Change the color tone of a shinytheme
但是,由于我对 CSS 了解不多,所以我正在努力解决这个问题。
这是一个可重现的例子:
library(shiny)
library(shinydashboard)
library(shinyWidgets)
library(shinymanager)
credentials <- data.frame(
user = c("shiny"),
password = c("shiny"),
stringsAsFactors = FALSE
)
css <- HTML(" body {
background-color: #0dc5c1;
}")
ui <- dashboardPage(
dashboardHeader(title = "Dashboard"),
## Sidebar content
dashboardSidebar(
sidebarMenu(
menuItem("App1", tabName = "App1", icon = icon("th"))
)
),
dashboardBody(
fluidRow(
tabItems(
tabItem(tabName = "App1",
sidebarPanel(
numericInput("num",
"Select a number",
min = 1,
value = 10),
sliderInput("slider1",
"Number of bins:",
min = 1,
max = 50,
value = 30),
checkboxInput("remove", "Remove...", value = FALSE),
),
mainPanel(
verbatimTextOutput("value"),
plotOutput("plot1"),
)
)
)
)
)
)
ui <- secure_app(ui,
# changing theme for the credentials
theme = shinythemes::shinytheme("united"),
tags_top = tags$div(
tags$head(tags$style(css)),
tags$img(
src = "https://marketplace.egi.eu/101-large_default/the-r-project-for-statistical-computing.jpg", width = 200, height = 200, alt="Logo not found", deleteFile=FALSE
))
)
server <- function(input, output, session) {
res_auth <- secure_server(
check_credentials = check_credentials(credentials)
)
}
shinyApp(ui, server)
我的objective是把登录页面的颜色改成#0dc5c1下面的颜色,特别是页面的边框和按钮。
我尝试添加:
css <- HTML(" body {
background-color: #0dc5c1;
}")
但是没用。
有人知道怎么解决吗?
非常感谢
我修改了CSS.
ui <- secure_app(ui,
# changing theme for the credentials
theme = shinythemes::shinytheme("united"),
tags_top = tags$div(
tags$head(
tags$style(
".row {
background-color: #0dc5c1;"
),
tags$style(
".panel-body {
background-color: #0dc5c1;"
),
tags$style(
".panel-auth {
background-color: #0dc5c1;"
)
),
tags$img(
src = "https://marketplace.egi.eu/101-large_default/the-r-project-for-statistical-computing.jpg", width = 200, height = 200, alt="Logo not found", deleteFile=FALSE
))
)
我不确定应该更改背景颜色的确切位置。如果太多,只需删除一些 CSS.
请检查以下内容:
library(shiny)
library(shinydashboard)
library(shinyWidgets)
library(shinymanager)
credentials <- data.frame(
user = c("shiny"),
password = c("shiny"),
stringsAsFactors = FALSE
)
css <- HTML(".btn-primary {
color: #ffffff;
background-color: #0dc5c1;
border-color: #0dc5c1;
}
.panel-primary {
border-color: #0dc5c1;
}")
ui <- dashboardPage(
dashboardHeader(title = "Dashboard"),
## Sidebar content
dashboardSidebar(
sidebarMenu(
menuItem("App1", tabName = "App1", icon = icon("th"))
)

dashboardBody(

checkboxInput("remove", "Remove...", value = FALSE),
),
mainPanel(
