Как сделать отзывчивый bootstrap элемент квадратным

Question

Я пытаюсь создать страницу для купонов, вот код HTML:

<!-- Content -->
<div class="section section-contents section-pad">
    <div class="container">
        <div class="content row">

            <div class="row row-feature row-column">
                <!-- Coupon Boxes -->
                <div class="col-md-4 col-sm-4">
                    <div class="feature boxed coupon">
                        <div class="fbox-content center">
                             <span class="scissors">
                                <i class="fa fa-scissors"></i>
                             </span>
                            <h2>Residential Plumbing</h2>
                            <p>Lorem ipsum dolor sit amet, conse ctetur adip isicing elit, sed do eius mod tempor incididunt fuga platea ut labore et.</p>
                            <p class="fineprint" >Valid Mon-Sat 7AM-7PM. Cannot be combined with any other offer<br>Offer Expires: <?php echo date("m/d/y",strtotime("last day of +0 month")); ?></p>
                        </div>
                    </div>
                </div>
                <!-- End Coupon box -->

                <!-- Coupon Boxes -->
                <div class="col-md-4 col-sm-4">
                    <div class="feature boxed coupon">
                        <div class="fbox-content center">
                             <span class="scissors">
                                <i class="fa fa-scissors"></i>
                             </span>
                            <h2>Residential Plumbing</h2>
                            <p>Lorem ipsum dolor sit amet, conse ctetur adip isicing elit, sed do eius mod tempor incididunt fuga platea ut labore et.</p>
                            <p class="fineprint" >Valid Mon-Sat 7AM-7PM. Cannot be combined with any other offer<br>Offer Expires: <?php echo date("m/d/y",strtotime("last day of +0 month")); ?></p>
                        </div>
                    </div>
                </div>
                <!-- End Coupon box -->


                <!-- Coupon Boxes -->
                <div class="col-md-4 col-sm-4">
                    <div class="feature boxed coupon">
                        <div class="fbox-content center">
                             <span class="scissors">
                                <i class="fa fa-scissors"></i>
                             </span>
                            <h2>Residential Plumbing</h2>
                            <p>Lorem ipsum dolor sit amet, conse ctetur adip isicing elit, sed do eius mod tempor incididunt fuga platea ut labore et.</p>
                            <p class="fineprint" >Valid Mon-Sat 7AM-7PM. Cannot be combined with any other offer<br>Offer Expires: <?php echo date("m/d/y",strtotime("last day of +0 month")); ?></p>
                        </div>
                    </div>
                </div>
                <!-- End Coupon box -->


            </div>
            <!-- End Feature Boxes -->

        </div>
    </div>
</div>
<!-- End content -->

Вот тот CSS, который я написал:

    .coupon{
        border-style: dashed;
        border-color: black;
        padding: 15px;
        min-height: 350px;
        vertical-align: middle !important;
    }

    .fineprint{
        font-size: 11px;
        vertical-align: bottom;
    }

    .scissors{
        font-size: 48px;
        color: #000;
        vertical-align: top;
    }

Я бы как коробки с пунктирными линиями, чтобы быть квадратным. На настольном компьютере и мобильном телефоне он выглядит красиво, но на планшете он не квадратный. Я хочу, чтобы это был идеальный квадрат независимо от формата. Как я могу это сделать? Заранее спасибо!

Вы можете сложить их на средний, маленький и очень маленький экран. Довольно сложно собрать их в один ряд со всем вашим контентом, не скрывая их.

      .coupon {
        border-style: dashed;
        border-color: black;
        padding: 15px;
        max-height: 320px;
        max-width: 320px;
        overflow: hidden;
        vertical-align: middle !important;
        margin: 10px;
      }

      .fineprint {
        font-size: 11px;
        vertical-align: bottom;
      }

      .scissors {
        font-size: 48px;
        color: #000;
        vertical-align: top;
      }
