<input maxlength=”text”>

<!DOCTYPE html>

background-image: linear-gradient(135deg, #8BC6EC 0%, #9599E2 100%);
text-align: center;
}
input {
width: 300px;
background: transparent;
border: 2px solid #fff;
outline: none;
display: block;
margin: 1rem auto;
border-radius: 20px;
padding: 8px 10px;
}
::placeholder {
color: #000;
}
.btn {
background: #db133a;
color: #fff;
border: none;
width: 320px;
}
</style>
<body>
