Solution

  • the trick is to use an inset shadow

    input {
  width: 80%;
  height: 30px;
  border: none;
  background: transparent;
  }
.shadow {
  box-shadow: inset 0px -1px 0px 0px #ccc;
  transition: 0.8s;
  }
.shadow:focus {
  box-shadow:inset 0px -3px 0px 0px #7777dd;
  outline: 0;
  }
    <input class="shadow" type="text" placeholder="Placeholder" />
