У Вас в стиле кнопки, зачем-то, есть body {, если его убрать -- всё работает:

<style>
  .custom-btn {
    width: 130px;
    height: 40px;
    color: #fff;
    border-radius: 5px;
    padding: 10px 25px;
    font-family: 'Lato', sans-serif;
    font-weight: 500;
    background: transparent;
    cursor: pointer;
    transition: all 0.3s ease;
    position: relative;
    display: inline-block;
    box-shadow: inset 2px 2px 2px 0px rgba(255, 255, 255, .5), 7px 7px 20px 0px rgba(0, 0, 0, .1), 4px 4px 5px 0px rgba(0, 0, 0, .1);
    outline: none;
  }
  
  .btn-9 {
    border: none;
    transition: all 0.3s ease;
    overflow: hidden;
  }
  
  .btn-9:after {
    position: absolute;
    content: " ";
    z-index: -1;
    top: 0;
