html - CSS 1px border stroke breaks around border radius

Question

This is for web dev. When using a 1px border radius on a circle or a square with really rounded corners, the stroke starts to break. If we were to change it to 2px's it would get better and better the more px we add. But is there a way to fix this problem with a 1px stroke?

background: rgba(32, 32, 32, .9);
height: 30px;
width: 30px;
border: 1px solid white;
border-radius: 20px;
:hover {
 height: 300px;
 width: 200px;
}

Answer 1

add box-shadow: 0 0 1px 0px white inset, 0 0 1px 0px white; that will give you the anti-aliasing you're looking for.
