Border radius issue

[Treasure]

Hello house.

My CSS border radius is not rendering on the image, not given it curved edges as I wanted.

Can anyone help with the right syntax for border-radius of a picture?

Thanks.

This is the syntax for border-radius of a picture (no need to copy the width and height properties) :

img{
width: 200px;
height: 200px;
border-radius: 50%;
}
