With shinyEffects, you will be able to customize the style of any elements.
Use the setShadow() function as shown below.
Code
  library(shiny)
  library(shinydashboard)
  library(shinydashboardPlus)
  library(shinyEffects)
  
  setShadow <- shinyEffects::setShadow
  setPulse <- shinyEffects::setPulse
  setShake <- shinyEffects::setShake
  setZoom <- shinyEffects::setZoom
  boxTag <- boxPlus(
   title = "Closable box, with label",
   closable = TRUE,
   enable_label = TRUE,
   label_text = 1,
   label_status = "danger",
   status = "warning",
   solidHeader = FALSE,
   collapsible = TRUE,
   p("Box Content")
  )
  shinyApp(
   ui = dashboardPagePlus(
     header = dashboardHeaderPlus(
       enable_rightsidebar = TRUE,
       rightSidebarIcon = "gears"
     ),
     sidebar = dashboardSidebar(),
     body = dashboardBody(
      setShadow(class = "box"),
      setShadow(id = "my-progress"),
      tags$h2("Add shadow to the box class"),
      fluidRow(boxTag, boxTag),
      tags$h2("Add shadow only to the first element using id"),
      tagAppendAttributes(
       verticalProgress(
        value = 10,
        striped = TRUE,
        active = TRUE
       ),
       id = "my-progress"
      ),
      verticalProgress(
        value = 50,
        active = TRUE,
        status = "warning",
        size = "xs"
      ),
      verticalProgress(
        value = 20,
        status = "danger",
        size = "sm",
        height = "60%"
      )
     ),
     rightsidebar = rightSidebar(),
     title = "DashboardPage"
   ),
   server = function(input, output) { }
  )Use the setZoom() function as shown below. You can choose the zoom level via the “scale” argument. By default, the zoom is 5% bigger than the original element size ( which is widely enough).
Code
  library(shiny)
  library(shinydashboard)
  library(shinydashboardPlus)
  library(shinyEffects)
  
  setShadow <- shinyEffects::setShadow
  setPulse <- shinyEffects::setPulse
  setShake <- shinyEffects::setShake
  setZoom <- shinyEffects::setZoom
  boxTag <- boxPlus(
   title = "Closable box, with label",
   closable = TRUE,
   enable_label = TRUE,
   label_text = 1,
   label_status = "danger",
   status = "warning",
   solidHeader = FALSE,
   collapsible = TRUE,
   p("Box Content")
  )
  shinyApp(
   ui = dashboardPagePlus(
     header = dashboardHeaderPlus(
       enable_rightsidebar = TRUE,
       rightSidebarIcon = "gears"
     ),
     sidebar = dashboardSidebar(),
     body = dashboardBody(
      setZoom(class = "box"),
      setZoom(id = "my-progress"),
      tags$h2("Add zoom to the box class"),
      fluidRow(boxTag, boxTag),
      tags$h2("Add zoom only to the first element using id"),
      tagAppendAttributes(
       verticalProgress(
        value = 10,
        striped = TRUE,
        active = TRUE
       ),
       id = "my-progress"
      ),
      verticalProgress(
        value = 50,
        active = TRUE,
        status = "warning",
        size = "xs"
      ),
      verticalProgress(
        value = 20,
        status = "danger",
        size = "sm",
        height = "60%"
      )
     ),
     rightsidebar = rightSidebar(),
     title = "DashboardPage"
   ),
   server = function(input, output) { }
  )Use the setPulse() function as shown below. You can choose the number of iterations (5 by default), as well as the pulse frequency (1 beat/s by default).
Code
  library(shiny)
  library(shinydashboard)
  library(shinydashboardPlus)
  library(shinyEffects)
  
  setShadow <- shinyEffects::setShadow
  setPulse <- shinyEffects::setPulse
  setShake <- shinyEffects::setShake
  setZoom <- shinyEffects::setZoom
  boxTag <- boxPlus(
   title = "Closable box, with label",
   closable = TRUE,
   enable_label = TRUE,
   label_text = 1,
   label_status = "danger",
   status = "warning",
   solidHeader = FALSE,
   collapsible = TRUE,
   p("Box Content")
  )
  shinyApp(
   ui = dashboardPagePlus(
     header = dashboardHeaderPlus(
       enable_rightsidebar = TRUE,
       rightSidebarIcon = "gears"
     ),
     sidebar = dashboardSidebar(),
     body = dashboardBody(
      setPulse(class = "box", duration = 1, iteration = 100),
      setPulse(id = "my-progress", duration = 1, iteration = 100),
      tags$h2("Add pulse animation to the box class"),
      fluidRow(boxTag, boxTag),
      tags$h2("Add pulse animation only to the first element using id"),
      tagAppendAttributes(
       verticalProgress(
        value = 10,
        striped = TRUE,
        active = TRUE
       ),
       id = "my-progress"
      ),
      verticalProgress(
        value = 50,
        active = TRUE,
        status = "warning",
        size = "xs"
      ),
      verticalProgress(
        value = 20,
        status = "danger",
        size = "sm",
        height = "60%"
      )
     ),
     rightsidebar = rightSidebar(),
     title = "DashboardPage"
   ),
   server = function(input, output) { }
  )Use the setShake() function as shown below. You can choose the shake frequency (0.82/s by default).
Code
  library(shiny)
  library(shinydashboard)
  library(shinydashboardPlus)
  library(shinyEffects)
  
  setShadow <- shinyEffects::setShadow
  setPulse <- shinyEffects::setPulse
  setShake <- shinyEffects::setShake
  setZoom <- shinyEffects::setZoom
  boxTag <- boxPlus(
   title = "Closable box, with label",
   closable = TRUE,
   enable_label = TRUE,
   label_text = 1,
   label_status = "danger",
   status = "warning",
   solidHeader = FALSE,
   collapsible = TRUE,
   p("Box Content")
  )
  shinyApp(
   ui = dashboardPagePlus(
     header = dashboardHeaderPlus(
       enable_rightsidebar = TRUE,
       rightSidebarIcon = "gears"
     ),
     sidebar = dashboardSidebar(),
     body = dashboardBody(
      setShake(class = "box"),
      setShake(id = "my-progress"),
      tags$h2("Add shake to the box class"),
      fluidRow(boxTag, boxTag),
      tags$h2("Add shake only to the first element using id"),
      tagAppendAttributes(
       verticalProgress(
        value = 10,
        striped = TRUE,
        active = TRUE
       ),
       id = "my-progress"
      ),
      verticalProgress(
        value = 50,
        active = TRUE,
        status = "warning",
        size = "xs"
      ),
      verticalProgress(
        value = 20,
        status = "danger",
        size = "sm",
        height = "60%"
      )
     ),
     rightsidebar = rightSidebar(),
     title = "Shake Effect"
   ),
   server = function(input, output) { }
  )You can combine all the previous effects according to your needs.
