Back in the 2000s, creative agency websites really liked the grid effect where you would hover over a block in a grid and that block would expand into some content.  Of course then, people would use Flash or some complicated jQuery contraption.  I created my own code example of this for a client once to demonstrate a CSS3 based design working with typical HTML element flow instead of overriding everything with position absolute and calculating block sizes on the fly.   This example also serves to teach how powerful CSS inheritance can be to create series of movements that look like fancy Javascript.

It’s not a perfect example because if a user mouseovers too quickly to the next block, the widths may exceed the row and break to the next line.  A solution could be to give some extra spatial buffer to the .main-content wrapper.   jQuery is still used here to trigger the next child block to be “hidden.” Since the transitions are set the same, one smoothly replaces the other.   At the end of the row, it triggers the previous child.
