How to make newline with "\n" in html and not with "br" tag?

Answer 1

You can't. Browsers ignore whitespace so toss them.

Answer 2

The \n character is used to find a newline character.

Can be done in JavaScript as in the example:

var str = "Visit sololearn.\nLearn Javascript.";
alert(str);

result:
Visit sololearn
Learn Javascript.
