The wrap attribute specifies how the text in a text area is to be wrapped when submitted in a form. The wrap attribute can be applied on the following HTML element: <textarea>.
<textarea wrap="soft|hard"></textarea>
soft: the text in the textarea is not wrapped when submitted in a form. This is default.
hard: the text in the textarea is wrapped (contains newlines) when submitted in a form. When "hard" is used, the cols attribute must be specified.

<form style="margin-left:3vw;" action="/action_page.php">
<textarea rows="3" cols="20" name="usrtxt" wrap="hard">In various places on my website you will

<input type="submit">
