pseudo-element affect clip-path - html

Question

I'm trying to do something seemingly easy but its not working out for me.
I have a simple button with a shimmer hover effect. I want have the same button effect applied to a button that is shaped like a hexagon. I thought I'd be pragmatic and just overlay the button with a clip-path (I don't care about the browser support). but, sadly the pseudo-element affect the clip-path making it unusable. Am I missing something simple? Or will the combination of these two never work?
.button {
outline:none;
border:none;
padding:20px;
display:block;
margin:0 auto;
cursor:pointer;
font-size:16px;
font-weight: bold;
background-color:#DBBD68;
text-transform: uppercase;
position:relative;
transition:all 0.5s ease;
overflow: hidden;
color:#fff;
&.hex{
width: 280px;
height: 280px;
position:absolute;
top: 0;
left:0;
-webkit-clip-path: polygon(20% 50%, 12% 60%, 20% 70%, 82% 70%, 89% 60%, 80% 50%);
clip-path: polygon(20% 50%, 12% 60%, 20% 70%, 82% 70%, 89% 60%, 80% 50%);
}
&:before {
content: '';
background-color: rgba(255,255,255,.5);
width:100%;
height:20px;
position:absolute;
left:-135px;
transform: rotateZ(45deg)
}
I made a Fiddle to showcase the issue: https://jsfiddle.net/0m5wmvu8/

You tried to do something crazy with .hex, but the only thing you should have added was the clip-path. Just change it to:
&.hex{
-webkit-clip-path: polygon(50% 0, 80% 0, 100% 50%, 80% 100%, 20% 100%, 0 50%, 20% 0);
clip-path: polygon(50% 0, 80% 0, 100% 50%, 80% 100%, 20% 100%, 0 50%, 20% 0);
}
