@jmarkmurphy, I believe probably you're unfamiliar Along with the phrase "perfectly-shaped" staying a technical jargon phrase to refer to the prerequisite towards the requirements of XML and XHTML that all tags will need to have closing tags and must be nested in the appropriate get.
Old Netscape usually required the " /" space prior to the slash or it failed. Who cares about previous browsers, appropriate? But its yet one more circumstance for my Variation I continue to like :)
Right after seeing this self-closing tag short article and examining code in console myself I arrived to realize that in HTML5 Even when you create or they're going to inevitably be converted to from the browser.
If you wish to use XML or XHTML, then you aren't making use of HTML and that is a different story. Will not make use of a closing slash for people HTML tags. Elsewhere, the spec states you'll be able to put just one there but it means nothing at all, does nothing and browsers are instructed to ignore it.
