Checkout this example:

#content {
  height: 300px;
  text-align: center;
  font-size: 26px;
  color: #000;
  position:relative;
}
.bg{
  position: absolute;
  left: 0;
  right: 0;
  top: 0;
  bottom: 0;
  z-index: -1;
  background: url(http://www.gstatic.com/webp/gallery/1.jpg) 0% 0% repeat;
  animation-name: MOVE-BG;
  animation-duration: 100s;
  animation-timing-function: linear;
  animation-iteration-count: infinite;
}
@keyframes MOVE-BG {
   from {
     transform: translateX(0);
   }
   to { 
     transform: translateX(-187%);
   }
}
