why and not ?

Question

This is one of those things that you read once, say \"aha!\" and then forget. Exactly my case.

Why is the line-break tag in xhtml preferentially written with a space

Answer 1

If I recall correctly it's simply because some older browsers had problems with a self-closing tag without a space before the slash. I doubt it's an issue nowadays, but a lot of developers (myself included) got into the habit of including the space.

Edit: Ah, here we are:

http://www.w3.org/TR/xhtml1/#guidelines

Include a space before the trailing / and > of empty elements, e.g.
,

---

and . Also, use the minimized tag syntax for empty elements, e.g.
, as the alternative syntax

allowed by XML gives uncertain results in many existing user agents.
