How to make a CSS3 Clip Path - css

Question

I want to make figure 1
like as figure 2
using clip path, is it possible?

Answer 1

clip-path is still a very experimental CSS3 element and therefore isn't very well supported and what support there is is minimal.
Using the CSS3 clip-path element to generate the polygon only allows for straight corners as its all point based rather than allowing for curves.
Heres an example:
body {
background: #555;
margin: 0;
}
img {
-webkit-clip-path: polygon(98% 0, 100% 2%, 100% 88%, 98% 90%, 25% 90%, 20% 99%, 15% 90%, 2% 90%, 0 88%, 0 2%, 2% 0);
clip-path: polygon(98% 0, 100% 2%, 100% 88%, 98% 90%, 25% 90%, 20% 99%, 15% 90%, 3% 90%, 0 88%, 0 2%, 2% 0);
}

Your best alternative would be to use an actual SVG element and reference it within the CSS to do the cut out. If you want a perfect shape but sadly no support on IE, this is the way to go.
SVG Only Version
body {
background: #555;
margin: 0;
}
img {
clip-path: url(#svgPath);
-webkit-clip-path: url(#svgPath);
}
<svg height="0" width="0">
<defs>
<clipPath id="svgPath">
<path fill="#FFFFFF" d="M50,0 L450,0 Q500,0 500,50 L500,400 Q500,450 450,450 L200,450 L175,500 L150,450 L50,450 Q0,450 0,400 L0,50 Q0,0 50,0z" />
