This is a vertical column layout that you can use in your next web design project. It was designed by Ettrics. The columns has a shimmering effect to it on hover and when you click on it, you will see that it opens up the hidden content in each column. When you view this on a smaller screen the layout switches from vertical to horizontal view.
