Type CardOptions
type CardOptions struct {
Size CardSize
// HeaderHeight and FooterHeight are the heights the caller needs for their
// content; the content section takes whatever is left.
HeaderHeight float32
FooterHeight float32
// HeaderBorder draws the header's border-b with a spacing of padding under
// its content; FooterBorder draws the footer's border-t with padding above.
HeaderBorder bool
FooterBorder bool
}CardOptions describes the sections of a card. All sizes are content heights in logical pixels; a zero height leaves the section out. The card supplies the padding around and between them (--card-spacing, which Size selects).
