Possible to round the canvas corners in Om?

I'm looking for if there's a way to round the corners of the canvas in the Om theme? Similar to how you have the option to round the corners of a button block. There's an example attached, the right side is what I'm aiming for. Thanks in advance for any insight.

Add this to your custom css area, after any other code that may already be there

#canvas {
    border-radius: 20px;
}

Then play with the radius value

that's perfect - thank you!
