 ul li {
        display: flex; 
        justify-content: center; 
        align-items: center; 
        background-color: #4095E5;

        transition: transform 0.3s, box-shadow 0.3s;
        position: relative;
        overflow: hidden;
    }

 ul li::before,  ul li::after {

        width: 100%;
        height: 100%;
        background: rgba(255, 255, 255, 0.3);
        transition: transform 0.3s;
    }

 ul li::before {
        transform: rotate(45deg);
    }

 ul li::after {
