如何叠加内嵌的CSS形状？

Question

I have been trying to create a Hexagonal border with pure CSS with a check mark in it.

I found Hexagon shape with a border/outline and the answer by JoshC worth pursuing. I created a fiddle an have been trying to get the shapes to behave inline. It is my intention to convert this to use em vs px after completion.

I can get two of the three to position correctly but not the third. I have not tried to get my check in the box yet. I have taken JoshC's CSS and created a base class to minimize duplicate settings. And have made progress but I have not succeeded. The basic premise is here, withe the fiddle being more involved. There is also a matter of white space below the shape.

<div class="hex hex1"></div>
<div class="hex hex2"></div>
<div class="hex hex3"></div>

Body{font-size:24px;}
.hex:before{content:"";width:0;height:0;border-bottom:30px solid #6C6;border-left:52px solid transparent;border-right:52px solid transparent;position:absolute;top:-30px;left:0;}
.hex{margin-top:30px;margin-bottom:30px;width:104px;height:60px;background-color:#6C6;position:relative;}
.hex:after{content:"";width:0;position:absolute;bottom:-30px;border-top:30px solid #6C6;border-left:52px solid transparent;border-right:52px solid transparent;left:0;}

.hex1:before{border-bottom:30px solid #6C6;border-left:52px solid transparent;border-right:52px solid transparent;}
.hex1{background-color:#6C6;position:relative;}
.hex1:after{border-top:30px solid #6C6;border-left:52px solid transparent;border-right:52px solid transparent;left:0;}

.hex2:before{border-bottom:30px solid red;border-left:52px solid transparent;border-right:52px solid transparent;}
.hex2{background-color:red;position:relative;top:0;-webkit-transform:scale(.6);-moz-transform:scale(.6);transform:scale(.6);z-index:3;}
.hex2:after{border-top:30px solid red;border-left:52px solid transparent;border-right:52px solid transparent;left:0;}

.hex3:before{border-bottom:30px solid blue;border-left:52px solid transparent;border-right:52px solid transparent;}
.hex3{background-color:blue;position:relative;top:-90px;-webkit-transform:scale(.8,.8);-moz-transform:scale(.8,.8);transform:scale(.8,.8);}
.hex3:after{border-top:30px solid blue;border-left:52px solid transparent;border-right:52px solid transparent;left:0;}

Updated my fiddle based on the answer by GCyrillus ! I added -webkit-transform:scale for chrome.

nest your element and use less relative/top : -xx ; it will stand in the flow much more easier
