Html <hr /> tag...

Question

if i write like <hr> then also horizontal line is created so what this (/) sign signifies?

Answer 1

The slash (/) at end of empty tags (those which doesn't have closing </tag>s) is not valid in Html5, even if it's supported and auto-corrected... it remains from bad habits, for being XHtml compatible which was requiring it, even if XHtml was abandoned since outcome of Html5...
