Hello @D666
replace your code with this code
.js.product-form__input input[type=“radio”] + label:hover {
background-color: #e9e9e9;
color: #515357;
outline: 1px solid #999;
}
let me know if it is worked.
Your answer is correct but it was not working for me when I posted because…I had placed the style for the :checked state above the style for**:hover. **
