html - How to make a circular image in css

Question

I'm very new to this sort of thing but this is my issue. I've looked through a couple of questions and it makes sense with how to make it circular but the image which is made circular is half cut off, is there a way of fixing this. I am using HTML and CSS.

circular_image {
  float: left;
  margin-left: 125px;
  margin-top: 20px;
  width: 200px;
  height: 200px;
  border-radius: 100%;
  overflow: hidden;
  background-color: blue;
}

Answer 1

Your css rule needs a . (if it applied with a class) or # (if it is applied with an id) at the start.

Also if you apply the rule to a container of the image you need to set the image to re-size accordingly to fit the circle;

Finally, 50% radius is all you need for a circle.

.circular_image {
  width: 200px;
  height: 200px;
  border-radius: 50%;
  overflow: hidden;
  background-color: blue;
  /* commented for demo
  float: left;
  margin-left: 125px;
  margin-top: 20px;
  */
  
  /*for demo*/
  display:inline-block;
  vertical-align:middle;
}
.circular_image img{
  width:100%;
}

with container

<div class="circular_image">
  <img src="http://placekitten.com/500/500"/>
</div>

directly on image

<img class="circular_image" src="http://placekitten.com/g/500/500"/>
