What if we need to add multiple line breaks?

Answer 1

Just use multiple < /br> tags. :)

Answer 2

then I can set the div over text after which I want many line breaks
and at last set height of div to be greater than that of content by no of linbreaks

Answer 3

If I need more than one line break I typically make a new <div>, and I usually nest the <div>'s that hold my text (or copy, or written content), whatever you want to call it.
