#' @description
#'
#' This theme has major vertical grids.

#'
#' @param legends
#' If the legend needs to be displayed, the input should be TRUE.
#' If the legend is not needed, the input should be FALSE.
#'
#' @param borders
#' If the border needs to be displayed, the input should be TRUE.
#' If the border is not needed, the input should be FALSE.
#' @import ggplot2 cowplot
#'
#' @export
#' @return
#' Returns a background theme with major vertical grids (ggplot2 output).
#' @examples
