How can the line feeds in scanner input be retained within an HTML element?

edit

To retain line feeds in scanner input within an HTML element, you can use the HTML tag <pre> (preformatted text) to preserve the original formatting of the input text.

Here's an example:

<pre>
  Enter your input:
  This is line one.
  This is line two.
  And this is line three.
</pre>

This will display the input exactly as entered, with line breaks preserved:

Enter your input:
This is line one.
This is line two.
And this is line three.
