I noticed a book I am reading uses <br /> instead of just <br>.
What is the purpose of using / in there?
If you're outputting HTML, just use <br>. If you're outputting XHTML (or XML for that matter), then all tags must be closed, so stand-alone tags such as BR and IMG must be self-closed with that final "/", thus the <br />.
Alright, thanks
Also take note that there's a space before the /
