Protector

Esta técnica utiliza valores de índice z negativos en algunos de los pseudoelementos. Eso significa que pueden ir detrás de otros elementos que tienen fondos opacos, lo que arruina el efecto. Para solucionar esto, deberá asegurarse de que el padre inmediato de las cintas no tenga un fondo aplicado y tenga una posición relativa con un índice z positivo. Use una envoltura adicional si es necesario.

<div class="non-semantic-protector"> 
   <!-- ribbons and other content in here -->
</div>
.non-semantic-protector { position: relative; z-index: 1; }
