When to use Pixels

In a previous lesson it seemed that px wasn't as good as em for styling.

Is there a rule of thumb for when it is best to use a particular unit?

When using pixels your using actual measurements. The em units are relative unit that is relative to the currently chosen font size.

Thanks Paul! I was wondering if there is a best practice for when to use each one?

Any insight is much appreciated
