  font-family: 'Sans', sans-serif !important;
  font-size: 50px !important;
  font-weight: 900 !important;
}
.container-fluid {
  width: 30% !important;

<div class="container">
  <div class="bloco">

      <h1 class="title">404</h1>
      <img class="img-fluid" src="https://cdn.dribbble.com/users/285475/screenshots/2083086/dribbble_1.gif" />
      <h3 style="postion : relative; top: 10%;">Estás Perdido?</h3>
