HTML: What's the correct form of BR?

Question

How is correct to write the br tag in html?

<br /> 

or

<br> 

or anything else? :))

Answer 1

It depends on the doctype you're using. In the original versions of HTML (up to HTML4), only <br> is correct. In XHTML (which is based on XML), only <br /> is correct. In HTML5, both are allowed although <br> is preferred.

Answer 2

It does not need an end tag, so

<br> 

is correct for HTML, and

<br /> 

for XHTML.
