div里有个p标签，想a:hover时先div展开完了再显示p可以怎么做？

<a href="#">hover
        <div class="div2">
            <p>qwerqwerqwer</p>
        </div>
    </a>

a:hover .div2{
        animation: 0.5s div2 ease-in forwards;    
    }
    a:hover p{
        display: block;
    }
    @keyframes div2{
        0%{height: 0; }
        100%{height: 200px; }
    } 
    .div2{
        width: 200px;
        background-color: red;
        
    }
    p{
        display: none;
    }

a:hover .div2{
        animation: 2.5s div2 ease-in forwards;    
    }
    a:hover p{
        display: block;
        animation: 0.5s div1 ease-in forwards;    
        animation-delay:2.5s;
    }
    @keyframes div2{
        0%{height: 0; }
        100%{height: 200px; }
    } 
    @keyframes div1{
        0%{opacity: 0; }
        100%{opacity: 1; }
    } 
    .div2{
        width: 200px;
        background-color: red;
        
    }
    p{
        opacity: 0;
        display: none;
    }

a:hover .div2{
        animation: 0.5s div2 ease-in forwards;    
    }
    a:hover p{
        animation: 0.5s p ease-in forwards;    
    }
    @keyframes div2{
        0%{height: 0; }
        100%{height: 200px; }
    } 
    @keyframes p{
      0%{opacity:0}
      100%{opacity:1}
    }
    .div2{
        width: 200px;
        background-color: red;
        
    }
    p{
        display: block;
        opacity:0;
    }

给p也加动画
