Black Border/Shadow/Outline that won't go away

[Fredautoparts]

I need help ASAP. This button I created has a black border, outline or shadow that I can't get rid of. I've tried everything I found already online but I might've done it wrong, so I'm open to any suggestions.

Liquid:

<a href="#" class="order-btn button">Place Order</a>

CSS: 

a.order-btn.button {
position: fixed;
display: inline-block;
right: 15px;
top: 90%;
border-radius: 28px;
font-family: Arial;
color: #000000;
font-size: 14px;
background: #f9dd33;
padding: 10px 30px 10px 30px;
margin-top: 20px;
font-size: 20px;
font-weight: medium;
z-index: 999;
}

a.order-btn.button:hover {
color: #ffffff;
background: #1890ff;
text-decoration: none;
}
