CSS

del,
strike {
  text-decoration: none;
  line-height: 1.4;
  background-image: -webkit-gradient(linear, left top, left bottom, from(transparent), color-stop(0.63em, transparent), color-stop(0.63em, #ff0000), color-stop(0.7em, #ff0000), color-stop(0.7em, transparent), to(transparent));
  background-image: -webkit-linear-gradient(top, transparent 0em, transparent 0.63em, #ff0000 0.63em, #ff0000 0.7em, transparent 0.7em, transparent 1.4em);
  background-image: -o-linear-gradient(top, transparent 0em, transparent 0.63em, #ff0000 0.63em, #ff0000 0.7em, transparent 0.7em, transparent 1.4em);
  background-image: linear-gradient(to bottom, transparent 0em, transparent 0.63em, #ff0000 0.63em, #ff0000 0.7em, transparent 0.7em, transparent 1.4em);
