立体的なボタン

押し込む

ホバー時に、少し立体的なボタンを凹ませて、クリックできることをわかりやすくします。

     width: 200px;
     height: 50px;
     border: 1px solid #000;
     color: #fff;
     display: flex;
     justify-content: center;
     align-items: center;
     background-color: #000;
     box-shadow: 5px 5px 0 #ccc;
     transition: all 0.3s;
}
.button:hover {
     cursor: pointer;
     box-shadow: unset;
     transform: translate(4px, 4px);
}
