Hi,

i am trying to apply box-shadow: -2px 10px 5px 0px rgba(0,0,0,0.75); to a box.

.myBox{
    background-color:#FFFFFF;
    padding: 5px;
    box-shadow: -2px 10px 5px 0px rgba(0,0,0,0.75);
}

but only getting white background and not the shadow, i am using openfl backend targeting html5.

are there any restrictions or limitations ?

i use Zeplin to get CSS for my components designs.
