The `:hover` // pseudo-class cannot be expressed using vanilla CSS-in-JS, so we define it // here. If we move the other properties to JS, they have higher precedence // as they are inline and the `:hover` `background` change won’t override the // base `background` definition. Revisit this as we adopt a more sophisticated // style system in the future: background: transparent; width: 50px; height: 50px; display: inline-block; cursor: pointer; border-radius: 50%; padding: 3px; &:before { content: ''; display: block; width: 100%; height: 100%; } &:hover { background: var(--gray-color); } &.save { &:before { @include color-svg('../images/save.svg', var(--white-color)); } } &.close { &:before { @include color-svg('../images/x.svg', var(--white-color)); } } }
