Add a triangular point to a div that changes with the content height with CSS?

Question

I have a div and I need to give it an angular point. The height will vary based on its content so using pseudo content and borders like in the article below wont work.

As this is a progressive enhancement I only need to support modern browsers.

Answer 1

An alternate answer, using gradients and pseudo elements

#one {height: 100px;}
#two {height: 200px;}
.corner {
    width: 100px;
    background-color: green;
    margin: 10px;
    position: relative;
}
.corner:after, .corner:before {
    content: "";
    position: absolute;
    left: 100%;
    width: 40px;
    height: 50%;
}
.corner:before {
    top: 0px;
    background: linear-gradient(to top right, green 50%, transparent 51%);
}
.corner:after {
    bottom: 0px;
    background: linear-gradient(to bottom right, green 50%, transparent 51%);
}

<div id="one" class="corner"></div>
<div id="two" class="corner"></div>
