Does anyone know how to create a css polygon that looks like this:

enter image description here



Solution :

I made a jsfiddle that may be helpful. I adapted it from this one: http://jsfiddle.net/76EUw/2/

Anyway, here's what I did:

.corner {
    width: calc(300px - 20px); /*300 is the width, 20 is the size of the 'cut'*/
    height: 0px;
    /*change the top/left depending on which corner you want to use*/
    border-top: 20px solid red; /*I made this red just so it was easier to see*/
    border-right: 20px solid white; /*not sure what you will do if this is not on a white background.*/
}
.main {
    width: 300px;
    height: 100px;
    background-color: black;
    color:white;
    text-align:center;
}
