In HTML5, do we still need the end slash like in XHTML?
<img src="some_image.png" />
validator.w3.org didn’t complain if I dropped it, not even a warning. But some online documents seem to indicate the end slash is still required for tags such as img, link, meta, br, etc.
imgtags are Void Elements so they do not need an end tag.…

That being said it’s not strict parsing in HTML5 so it won’t do any major harm.
