I used <br> and </br> instead of <br/>. But why it makes no change in the output?

Answer 1

br tag is used for single line breaks

Answer 2

HTML ignores your </br> as it has no knowledge of it. <br> and <br/> are equivalent to it. XHTML is where you must use <br/> as it requires each tag to have a close or, when there is no close, you add the / in the tag to show that fact.

Answer 3

Both are used for same purpose.

It uses for single line breaks.
