Absolute positioning an element on the circumference of a circle

I have been working on to place an icon to the bottom right of an image having the property of border-radius: 50%. Here's what I want to achieve(Icon to be on the circumference),

enter image description here

By absolute and relative positioning, I can place the icon as expected but on smaller screens, the icon goes out of place due to image resizing (with img-fluid class of bootstrap 4).

enter image description here

How can I make the icon to be at the same place across all screens even after image resizes?

.wrapper{
  position: relative;
  display: inline-block;
  margin: 30px;
}

.image{
  border-radius: 50%;
}

.icon{
  height: 50px;
  width: 50px;
  background: #008080;
  position: absolute;
  border-radius: 50%;
  right: 22px;
  bottom: 42px;
}
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet"/>

<div class='wrapper'>
  <img src='https://via.placeholder.com/350x350' class='image img-fluid'/>
  <span class='icon'></span>
</div>

Solution

  • Define right and bottom as % not px
    Do the same for height and width if you want size to adapt. See my snippet

    .wrapper{
  position: relative;
  display: inline-block;
  margin: 30px;
}

.image{
  border-radius: 50%;
}

.icon{
  height: 15%;
  width: 15%;
  background: #008080;
  position: absolute;
  border-radius: 50%;
  right: 10%;
  bottom: 5%;
}
    <link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet"/>

<div class='wrapper'>
  <img src='https://via.placeholder.com/350x350' class='image img-fluid'/>
  <span class='icon'></span>
</div>
