Circle div balloon

Question

Here is my current css for image circle baloon

.circle-image{
    width: 64px;
    height: 64px;
    border-radius: 50%;
    background-size: contain;
    background-position: center;
    background-image: url("/assets/img/dashboard/img-stdn.png");
    display: block;
}

And the div output as below:

How I can border the div and become like this?

Let say the image inside the div :

Answer 1

You could use a pseudo element in order to create your speech bubble triangle, as shown in the demo below.

This works by using a skew on a square, and position it absolutely within a relatively positioned container element.

Alternatively, this could be achieved with a single element if you were able to use the background-image instead of an image tag.

.circ {
  height: 100px;
  width: 100px;
  border-radius: 50%;
  bordeR: 5px solid tomato;
  position: relative;
}
.circ img {
  position: absolute;
  top: 0;
  left: 0;
  height: 100%;
  width: 100%;
  border-radius: 50%;
}
.circ:before{
  content:"";
  position:absolute;
  top:10%;
  right:0;
  height:20px;
  width:20px;
  background:tomato;
  transform:skewX(55deg) skewY(10deg);
  }

<div class="circ">
  <img src="http://i.stack.imgur.com/lCp2t.png" />
</div>

for more info in generating the triangle, you may find this quite a useful demonstration of how to achieve this triangle.

Background-image

By using a background-image instead, you can make this with only a single element.

.circ {
  position: relative;
  height: 100px;
  width: 100px;
  border-radius: 50%;  
  border: 5px solid tomato;
  background:url(http://i.stack.imgur.com/lCp2t.png);
  background-size:100% 100%;
}
.circ:before{
  content:"";
  position:absolute;
  top:10%;
  right:0;
  height:20px;
  width:20px;
  background:tomato;
  transform:skewX(55deg) skewY(10deg);
  z-index:-1;
  }

<div class="circ"></div>
