How to echo our a line break

Question

I am trying to echo out a line break by using <br></br> but can't seem to get it to display a line break.

I tried to use the <br></br> command

<?php
$sql = "SELECT * FROM review;";

$stmt = mysqli_stmt_init($conn);
//Prepare the prepared statement
if (!mysqli_stmt_prepare($stmt, $sql)) {

} else {
     //Bind parameters to the placeholder
     //Run parameters inside database
     mysqli_stmt_execute($stmt);
     $result2 = mysqli_stmt_get_result($stmt);
     $resultCheck2 = mysqli_num_rows($result2);

     while ($row2 = mysqli_fetch_assoc($result2)) {

      echo '<div class="review_post">';

      echo ' <i class="fas fa-quote-left"></i>'.htmlspecialchars($row2['review']).' '.htmlspecialchars($row2['user_uid']).' '.htmlspecialchars($row2['datesubmitted']).'<i class="fas fa-quote-right"></i>';
      echo '<br></br>';
       echo '<br></br>';
        echo '<br></br>';
      echo '</div>';

}

I expected to display all the reviews in separate line but it is all squashed up.

This is the CSS:

div.review_post {
  position: absolute;
  font-size: 3em;
  left: 8em;
  top: 130em;
  line-height: 5em;
  margin-bottom: 20em;
  white-space: nowrap;
}
