Denne teknik bruger negative z-indeksværdier på nogle af pseudoelementerne. Det betyder, at de kan gå bag andre elementer, der har uigennemsigtig baggrund, hvilket ødelægger effekten. For at løse dette skal du sørge for, at den umiddelbare forælder til båndene ikke har en baggrund anvendt og har relativ positionering med positivt z-indeks. Brug om nødvendigt en ekstra indpakning.
