        display: flex;
        height: 200px;
        width: 200px;
        background-color: red;
        justify-content: center;
        align-items: center;
        /* transition-property: background-color;
        transition-duration: 1s;
        transition-timing-function: ease-in-out;
        transition-delay: 2s; */

        /* Transition short hand property in one line */
        /* transition: background-color 1s ease-in-out 2s; */
