Change tooltip color

[analytichealth]

Hi, the package looks great. Is there any way to change the colours of the tooltips, by adjusting css maybe? Thanks

Hello, yes it is possible through CSS, but only for each tooltip type. You need to specify a type (e.g "error") in add_prompt(), and to include some CSS for this type. For example:

library(prompter)
library(shiny)

ui <- fluidPage(

  use_prompt(),
  tags$head(
    tags$style(
      HTML(
        ".hint--error:after {
          background-color: blue;
          text-shadow: 0 -1px 0px blue;
        }
        .hint--error.hint--bottom:before {
          border-bottom-color: blue
        }
        .hint--error.hint--left:before {
          border-left-color: blue
        }
        .hint--error.hint--top:before {
          border-top-color: blue
        }
        .hint--error.hint--right:before {
          border-right-color: blue
        }"
      )
    )
  ),
  add_prompt(
    actionButton("plot", "click"), 
    position = "bottom", message = "this is a button", type = "error"
  )
)

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

shinyApp(ui, server)

Therefore, for now, you can only have 4 different colors for tooltips at the same time (because there are 4 types).

This works great, thank you!
