CSS circles without width or height? : Is this possible with pure CSS or not?

Question

I can turn a div into a circle like this:

.circle {
 background-color: rgba(0, 0139, 0139, 0.5);
 height: 200px;
 width: 200px;
 -moz-border-radius:50%;
 -we         


        

Answer 1

All you need to do is replace you height and width with a padding and display inline-block. Reference: http://jsfiddle.net/6mzP7/

.circle {
   background-color: rgba(0, 0139, 0139, 0.5);
   padding: 200px;
   display: inline-block;
   -moz-border-radius:50%;
   -webkit-border-radius: 50%;
   border-radius:50%; 
}

​

The HTML can stay the same.
