Adding a 'close' button

function goBack() {
  if (document.referrer == "") {
  } else {
    window.location.href = ""

I wanted to create a button with a “close” icon for my website that would make the feeling of going back to the home page feel light and easy. The homepage is fairly long, so I also wanted it to return to the same scroll position it was in when the user clicked. Solution, <a href="javascript:history.back()">Back</a>. Problem is, what if someone got to the page by following a link from another site, or what if I want to email someone a link to a page?

Then we want the button to be a regular link to the homepage. Result above, activated by <a class="close-button" href="#" onclick="goBack(); return false;" ></a>. This CSS makes a nice fixed circle with a close ‘X’ icon in the top right corner:

.close-button {
  position: fixed;
  top: 20px;
  right: 20px;
  width: 50px;
  height: 50px;
  border-radius: 25px;
  background-color: rgba(255, 255, 255, 0.9);

.close-button:after {
  content: "";
  position: absolute;
  width: 34px;
  height: 2px;
  background-color: black;
  top: 24px;

.close-button:before {
  -webkit-transform: rotate(45deg);
  -moz-transform: rotate(45deg);
  transform: rotate(45deg);
  left: 8px;

.close-button:after {
  -webkit-transform: rotate(-45deg);
  -moz-transform: rotate(-45deg);
  transform: rotate(-45deg);
  right: 8px;
