# Split Slider

> Full-bleed slider that tears each photo down the middle. The left half slides one way and the right half the other while the next photo's halves cross in to meet at the seam. The giant title sits across the seam, so it splits and rejoins with the picture. A seam badge counts down to the next slide. Swipe, keys or tabs.
