#' Bulma Message
#'
#' Creates a message box with optional title bar.
#'
#' @param ... Message body
#' @param header Message header
#' @param delete Should delete button be displayed in upper right corner?
#' @param size Text size, one of `"small"`, `"normal"` (default),
#'  `"medium"`, or `"large"`.
#' @param width Width of the message. If `NULL` then width is 100% of container.
#'   If specified, the message is wrapped in a `column` div (see [bulma_column()]
#'   for more information and for valid column sizes).
#' @param centered Should the message container be centered horizontally?
#'   Requires `width` to be specified. If `TRUE`, the message container is
#'   inside a `column` div inside a `columns` div.
