使用自定义元框，我将如何在页面中显示背景图像（如果没有链接图像，则显示颜色）。

要显示数据的页面的代码。我想将背景色/图像应用于节id=“刊头”。

<?php if (get_post_meta($post->ID, \'_sqcmb_masthead_select\', true)) { ?>

</div><!--end #container .row (from header)-->
    <section id="masthead">
        <div class="row">
            <div class="large-9 large-centered columns">
                <?php
                    $content = get_post_meta( $post->ID, \'_sqcmb_masthead_content\', true );
                    echo do_shortcode( $content );
                ?>
            </div><!-- .large- centered columns -->
        </div><!-- .row -->
    </section><!-- #masthead -->

<!--restart #container .row (from header)--><div id="content" class="row">

<? } else { ?>
<?php } ?>
