Neon Style Rotating Borders with Pure CSS/CSS3

In this article we’re going to create neon style rotating borders for an Html element using CSS3 transforms and transitions.

How to use it:

Create four empty DIV elements for the borders.

<div class="rotate">
  <div class="line"><i></i></div>
  <div class="line"><i></i></div>
  <div class="line"><i></i></div>
  <div class="line"><i></i></div>
</div>

The core CSS/CSS3 for the rotating borders.

.rotate .line {
  width: 100%;
  height: 100%;
  display: block;
  position: absolute;
}
.rotate .line:nth-of-type(1) {
  -webkit-transform: rotate(0deg);
  -ms-transform: rotate(0deg);
  transform: rotate(0deg);
}
.rotate .line:nth-of-type(2) {
  -webkit-transform: rotate(90deg);
  -ms-transform: rotate(90deg);
  transform: rotate(90deg);
  margin-left: 60px;
}
.rotate .line:nth-of-type(3) {
  -webkit-transform: rotate(180deg);
  -ms-transform: rotate(180deg);
  transform: rotate(180deg);
}
.rotate .line:nth-of-type(4) {
  -webkit-transform: rotate(270deg);
  -ms-transform: rotate(270deg);
  transform: rotate(270deg);
  margin-left: -60px;
}
.rotate .line i {
  left: 0;
  top: 0;
  width: 200%;
  display: block;
  position: absolute;
  border-bottom: 5px dashed;
  -webkit-animation: move 3.5s infinite linear;
  animation: move 3.5s infinite linear;
}
.rotate .text {
  width: 210px;
  line-height: 80px;
  display: block;
  text-align: center;
  position: absolute;
  font-size: 40px;
}
@-webkit-keyframes 
move {  from {
 -webkit-transform: translateX(0%);
 transform: translateX(0%);
}
to {
  -webkit-transform: translateX(-50%);
  transform: translateX(-50%);
