Dropdown menu background hover only around text

Issue

Im quite new to this so very sorry for the basic questions! I'm currently trying to create a dropdown menu within my navigation bar and having a little trouble trying to trouble shoot why my background hover in my sub-menu only displays from the left of the box to the end of the text and not across the complete box. I have a felling it has something to do with the padding in my anchor? Thanks and appreciate all the help!

/*Bottom Navigation*/

    .BottomNav{
     background: #fac2ad;
     overflow: hidden;
     display: flex;
     justify-content: center;
     }
    .BottomNav li{
     display: inline;
     }
     .BottomNav a{
     float: left;
     color: #000;
     text-align: center;
     text-decoration: none;
     font-family: macho,sans-serif;

     font-size: 2rem;
     text-shadow: 0px 2px 2px rgba(0, 0, 0, 0.527);
   
    }
    .BottomNav:hover .dropDown:hover .dropButton{
    background-color: white;
    transition: 0.8s ease-out;

    .dropDown {
