I got your query, I think below mentioned code is the solution for your query.

 @import url('https://fonts.googleapis.com/css?family=Poppins:100,200,300,400,500,600,700,800,900'); *{ margin: 0; padding: 0; box-sizing: border-box; font-family: 'Poppins', sans-serif; } body{ display: flex; justify-content: center; align-items: center; min-height: 100vh; background-color: #0e1538; }.container{ display: flex; justify-content: center; align-items: center; flex-direction: column; }.container a{ position: relative; width: 160px; height: 60px; display: inline-block; background-color: #fff; margin: 20px; }.container a:before, .container a:after{ content: ''; position: absolute; inset: 0; /* background: #f00; */ background: linear-gradient(45deg,#00ccff,#0e1538,#0e1538,#d400d4); transition: 0.2s; }.container a:hover:before{ inset: -3px; }.container a:hover:after{ inset: -3px; filter: blur(10px); }.container a span{ position: absolute; top: 0; left: 0; width: 100%; height: 100%; display: inline-block; background: #0e1538; z-index: 10; display: flex; justify-content: center; align-items: center; font-size: 1.2em; text-transform: uppercase; letter-spacing: 2px; color: #fff; }
