Coding Question

What is the difference between <br>, <br/>, and <br />?

They all give the same results, but <br/> and <br /> (which are the actually the same thing with just a space, which makes no difference) abide by html standards.

So we should use <br/> over <br> and <br />?

<br/> or <br />
Personally, I prefer it with the space. Makes it look nicer.

Technically, <br> abides by the HTML spec while <br/> and <br /> abide by the XHTML spec. It is always better to use the XHTML spec because it is the stricter of the two. If it works in XHTML, it will work in HTML. The reverse is not true.
