reproducible example, note that action button can be styled directly by using #action selector however slider input has container therefore positioning of the slider as such should be done at container level and cannot be done by selecting id. As far as i know css selector doesnt have equivalent of jquery :has()
library(shiny)
shinyApp(
ui <- fluidPage(
fluidRow(actionButton("action", "Action"),sliderInput("x", "X", 1, 100, 50)),
tags$head(
tags$style('#action { margin:3px;border:2px solid green;padding 20px;}
.slider-custom-format { margin:3px;border:1px solid red;}
.slider-custom-format .irs-bar,.slider-custom-format .irs-bar-edge{background:red;}'),
tags$script('$(function(){
$(".form-group.shiny-input-container:has(#x)").addClass("slider-custom-format")
})')
)
),
server <- function(input, output) {})
