a:hover .p2{
        animation: 0.5s p2 ease-in forwards;    
    }
    a:hover p{
        animation: 0.5s p ease-in forwards;    
    }
    @keyframes p2{
        0%{height: 0; }
        100%{height: 200px; }
    } 
    @keyframes p{
      0%{opacity:0}
      100%{opacity:1}
    }
    .p2{
        width: 200px;
        background-color: red;
        
    }
    p{
        display: block;
        opacity:0;
    }

Add animation to p
