Should I be using span style, or div style?

How come you don’t put a display property on div, I thought they are required to have one?

And then I read this:

Does and should [display values] be put on every style tag?

One does not need to add a {display:value} statement to elements whose default display is not being changed.

So, I guess the div tag in this code doesn’t need a display value then.
