--description--

Your cat photo currently has sharp corners. We can round out those corners with a CSS property called border-radius.

--instructions--

You can specify a border-radius with pixels. Give your cat photo a border-radius of 10px.

Note: This challenge allows for multiple possible solutions. For example, you may add border-radius to either the .thick-green-border class or the .smaller-image class.

--hints--

Your image element should have the class thick-green-border.

js
assert.isTrue(document.querySelector('img').classList.contains('thick-green-border'));

Your image should have a border radius of 10px.

js
const image = document.querySelector('img');
const style = window.getComputedStyle(image);  
const borderTopLeftRadius = style['border-top-left-radius']; 
const borderTopRightRadius = style['border-top-right-radius'];
const borderBottomLeftRadius = style['border-bottom-left-radius'];
const borderBottomRightRadius = style['border-bottom-right-radius'];

assert.strictEqual(borderTopLeftRadius, '10px');
assert.strictEqual(borderTopRightRadius, '10px');
assert.strictEqual(borderBottomLeftRadius, '10px');
assert.strictEqual(borderBottomRightRadius, '10px');
