Setting the z-index ​
The z-index property specifies the stack order of an element. An element with greater stack order is always in front of an element with a lower stack order. Here are some examples of how to use these classes:
html
<div class="relative h-3xs w-full">
<div class="[ surface-container-highest left-1/12 ] index-overlay">Overlay</div>
<div class="[ surface-container-high left-2/12 ] index-scrim">Scrim</div>
<div class="[ surface-container left-3/12 ] index-fab">FAB</div>
<div class="[ surface-container-low left-4/12 ] index-surface">Surface</div>
<div class="[ surface-container-lowest left-5/12 ] index-pullback">Pullback</div>
</div>
