如何製作類似的東西?帶透孔的半透明覆蓋/掩膜
我試圖用3周的div position: absolute
(和它們的2 transformation: skew(...)
)。它有效但不完美。例如在IE中,頂部和底部div之間存在一定的空間(我不能將一個放在另一個之上,因爲顏色會變得更暗),左側和右側也會傾斜(儘管它可能通過添加兩個白色這裏的div)

.container {
padding: 15px;
margin-bottom: 30px;
position: relative;
}
.mask {
background: rgba(0, 0, 0, 0.78);
position: absolute;
z-index: 99;
}
.mask-top {
top: 0;
left: 0;
width: 100%;
height: 70%;
}
.mask-left {
width: 43%;
height: 30%;
left: 0;
bottom: 0;
margin-left: -24px;
transform: skew(-16deg);
}
.mask-right {
width: 43%;
height: 30%;
right: 0;
bottom: 0;
margin-right: -24px;
transform: skew(16deg);
}
</style>
</head>
<body>
<div class="container">
<img src="http://i.imgur.com/cnvTRdz.png"/>
<div class="mask mask-top"></div>
<div class="mask mask-left"></div>
<div class="mask mask-right"></div>
</div>
</body>
</html>

有沒有什麼更好的辦法?除了在IE中不支持的CSS遮罩。
UPD:
這裏是工作液(用SVG,如答案建議)
