I have designed a quiz on html with post php. Everything is fine but i do not know how to make the results in the center of the page. The results are on the left What's the best way to do this? I'm new to PHP. I have tried
results {
    text-align: center;
    }
and 
.results
{
    text-align: center;
    }
 echo "<div id='results'>$totalCorrect / 5 correct</div>";              ?>
                </div>
            </div>
        </div>
<div class="row">
        <div class="box">
            <div class="col-lg-12">
                <hr>
                <h2 class="intro-text text-center">How did you do?
                </h2>
                <hr>
                <hr class="visible-xs">
         <?php
        $answer1 = $_POST['question-1-answers'];
        $answer2 = $_POST['question-2-answers'];
        $answer3 = $_POST['question-3-answers'];
        $answer4 = $_POST['question-4-answers'];
        $answer5 = $_POST['question-5-answers'];
        $totalCorrect = 0;
        if ($answer1 == "B") { $totalCorrect++; }
        if ($answer2 == "A") { $totalCorrect++; }
        if ($answer3 == "C") { $totalCorrect++; }
        if ($answer4 == "D") { $totalCorrect++; }
        if ($answer5) { $totalCorrect++; }
        echo "<div id='results'> $totalCorrect / 5 correct </div>";
        ?>
            </div>
        </div>
    </div>
