Circle button css

Question

I'm a beginner and very confused, as a div tag when I give the same width and height with border-radius: 50% it always becomes circle. but with the tag a in case I want to make a circle button, It doesnt work that way. This is when I try to make a circle border button clickable.

<a class="btn" href="#"><i class="ion-ios-arrow-down"></i></a>


.btn {
  height: 300px;
  width: 300px;
  border-radius: 50%;
  border: 1px solid red;
}

Answer 1

Add display: block;. That's the difference between a <div> tag and an <a> tag

.btn {
      display: block;
      height: 300px;
      width: 300px;
      border-radius: 50%;
      border: 1px solid red;
    }
