Description

Currently, implementing a layout like the one below is a little tricky and would be easier if it was flex by default...all you'd have to know is add a margin-left: auto to the 1st item that you want to be right aligned

card(
    card_header(
      "Penguin body mass",
      tooltip(
        bsicons::bs_icon("question-circle"),
        "Mass measured in grams.",
        placement = "right"
      ),
      popover(
        bsicons::bs_icon("gear", class = "ms-auto"),
        selectInput("yvar", "Split by", c("sex", "species", "island")),
        selectInput("color", "Color by", c("species", "island", "sex"), "island"),
        title = "Plot settings"
      ),
      class = "d-flex align-items-center gap-1"
    ),
    plotOutput("plt")
)

Research direction

Start by locating the card_header() implementation and its SCSS styling in the bslib repository, then inspect how Bootstrap card headers are rendered. The change is complete when card headers use flex layout by default and the layout shown in the issue works without requiring an explicit flex class.
