I my working experience, I haven't encounter a case where working with is problematic, however, there are lots of conditions in which or In particular might be problematic in more mature browsers and applications.
The one thing that matters During this discussion is always to Constantly use coding that also transpires to adhere to XML specifications and also HTML specifications when feasible. Meaning you should use the correct XML Model of the break tag and stimulate all your crew to perform a similar:
To apparent up confusion: Placing a space prior to the slash just isn't expected in HTML5 and isn't going to make any change to how the web site is rendered (if anybody can cite an case in point I will retract this, but I don't believe it's correct - but IE undoubtedly does many other odd matters with all sorts of tags).

I've tried using examining other answers, but I'm even now baffled — Particularly following seeing W3schools HTML 5 reference.
@BasilBourque, I feel This may be provided by that mainly the answer's 1st sentence is extremely temporary / deceptive: " is adequate but in XHTML is preferred ..." => 1 could infer Which may be used in XHTML, which isn't truth of the matter.
