No. Borders sit on the outside of the element and on the inside of the box-model margin area. Outlines sit on the inside of the element and the box-model padding area ignores it.

How do you add a border-radius to an outline in CSS?

and the border-radius needs to be larger than the border width or the interior (background) will be square. If there is no other way to radius an outline then you can use the box shadow. Box shadow follows the shape of the element.

Is there an outline radius CSS?

The outline-radius property is used to specify the radius of an outline. It is used to give rounded corners to outlines.

Can you make a circle with border-radius?

To create a circle we can set the border-radius on the element. This will create curved corners on the element. If we set it to 50% it will create a circle. If you set a different width and height we will get an oval instead.


Try using CSS-Tricks' Infinite Borders technique and applying border-radius.

This method will require borders and box-shadow and not outline.

Dog with infinite rounded borders!

img {
    border-radius: 4px;
    /* #1 */
    border: 5px solid hsl(0, 0%, 40%);
    
    /* #2 */
    padding: 5px;
    background: hsl(0, 0%, 20%);
    
    /* #3 
    outline: 5px solid hsl(0, 0%, 60%); */
    
    /* #4 AND INFINITY!!! (CSS3 only) */
    box-shadow:
        0 0 0 10px red,
        0 0 0 15px orange,
        0 0 0 20px yellow,
        0 0 0 25px green,
        0 0 0 30px blue;
    
        
    /* If you could do pseudo elements 
       you could get a few more... */
    
    /* Also, HSL is awesome but don't use it if
       you need super old browser support */
}

body { padding: 50px; text-align: center; }

Firefox has a property -moz-outline-radius, however the request to implement a similar feature in WebKit was closed as WONTFIX. The plan for the future is to make the outlines follow the borders.

I realize this doesn't help much, but the answer to your question is: currently, no (not in a cross browser way). In the meantime you should use an alternative approach like the one suggested by thekalaban.
