I had a client who wanted to change her social icons from sharing buttons to linking buttons. She really liked her current button style which had a special rubber band effect directly on the icon (not the whole button), and wanted to keep it. The problem was that I couldn’t find a plugin with the same effect, so I hand-coded them. When you mouse over them, the icon wiggles. It reminds me more of jello than a rubber band. It was a fun little project!
Now, if you are viewing them on a cell phone or tablet, you won’t have the privilege of seeing the effect except on your return to the page from the linked page, since these devices don’t us a mouse. I liked them so much that I added them to my footer at the bottom of my pages.
