When using :hover (increases the block), how to avoid shifting neighboring blocks?

Question

Layout

When hovering over icons (twitter, facebook, linkedin), they should be enlarged using :hover. The problem is that when :hover fires, adjacent elements move. How is this situation resolved?

Answer 1

1 - Do not change the width, but use transform: scale
2 - Add position: absolute to the elements (and fix the width and position: relative to the parents)
