<center> and the solutions in this post are not equivalent ...

The HTML center tag only horizontally centers the contents which you can do with the simple CSS: `text-align:center` [1]

The examples in this post center horizontally AND vertically.

text-align:center does NOT entirely replicate <center>. And has been a source frustration for many.

that's fair, but <center> and this post are still not equivalent at all.
