                background-image: url('https://hi-news.ru/wp-content/uploads/2015/01/Galaxy.jpg');
            }
        </style>

        <div class="image"></div>

but in this case, no.

<style>
            .image {
                width: 100px;
                height: 100px;
                background-image: url('https://hi-news.ru/wp-content/uploads/2015/01/Galaxy.jpg');
