Opencart 3.0.3.8 带 flex 的默认主题

Question

我想在我的 Opencart 3.0.3.8 上使用默认主题添加此代码，但无法正常工作... 我为此代码使用“HTML 内容模块”

<section class="benefits">
                    <div class="row">

                        <div class="info-box col-lg-4 col-md-4 col-sm-12 d-flex">
                            <div class="info-box-inner bordered clearfix d-flex col-12">
                                <div class="icon fa fa-truck"></div>
                                <div class="info-box-text">
                                    <h4><span>TRANSPORT GRATUIT</span>
                                        pentru comenzile
                                        ce depasesc <i>500 lei</i></h4>
                                </div>

                            </div>
                        </div><!-- end info-box -->

                        <div class="info-box col-lg-4 col-md-4 col-sm-12 d-flex">
                            <div class="info-box-inner bordered d-flex col-12 clearfix">
                                <div class="icon fa fa-gift"></div>
                                <div class="info-box-text">
                                    <h4><span>OFERTE SPECIALE</span>

                                </div>

                            </div>
                        </div><!-- end info-box -->
                        <div class="info-box col-lg-4 col-md-4 col-sm-12 d-flex">
                            <div class="info-box-inner bordered clearfix col-12 d-flex">
                                <div class="icon fa fa-calendar"></div>
                                <div class="info-box-text">
                                    <h4><span>GARANTIA CALITATII</span>

                                        poti returna produsele</h4>
                                </div>

                            </div>
                        </div><!-- end info-box -->

                    </div><!-- end row -->
            </section>
