But that would require you to modify the markup. It would also stops you from having general styles declarations. You couldn't do .button{color:red;border: 1p

But that would require you to modify the markup. It would also stops you from having general styles declarations. You couldn't do .button{color:red;border: 1px solid white;} and then .box>.button{width:100%;} unless you make your markup <span class="button pricebox--box__button"> and that would be pretty ugly, wouldn't it? Correct me if I am wrong.
