Once we are writing the text it gets wrapped to next line
depending upon size of browser window but we can forcible put line break by giving BR tag
So after line break we are on new line
here we have created NOBR block where we are going on typing text
but it will not wrap automatically until we are giving BR tag.
The text will be too long to fit in window still it will write on same line.
WBR tag in NOBR block inserts again a Word break
