title: Border-radius: 50% produces jagged circles; why not perfect circles?
body: <p>I found other threads with similar titles, but I couldn't find a solution that works for me in those threads.</p>
  
  <p>I'm trying to produce input labels that are perfect circles by combining equal width/height with border-radius:50%, but the edges come out pixelated. I've tried various pixel values (both even and odd) for width/height, but the problem remains.</p>
  
  <p>How do I make the circles perfect?</p>
