Question

每个div都会获取我已上传到WordPress的背景图片。我希望能够以任何分辨率上传图像以用作背景图像，同时保持每个div处于相同的高度。

HTML：

<?php get_header(); ?>

<div class="row portfolio-content">
  <?php if(  have_posts() ) : while (  have_posts() ) :  the_post(); ?>
    <div class="col-xs-12 col-sm-6 col-md-4 portfolio-item">
      <a href="#">
         <img src="<?php echo 
         wp_get_attachment_url(get_post_thumbnail_id()); ?>" alt="">
      </a>
    </div>
  <?php endwhile; endif; ?>
</div>

<?php get_footer(); ?>

萨斯/ CSS：

 .portfolio-content{
  .portfolio-item{
    @include global-box-shadow;
    @include global-div-spacing;
    background: $white;
    text-align: center;
    padding: 2rem;
    a{
      position: relative;
      text-decoration: none;
      img{
       width: 100%;
     }
    }
   }
  }

一种方法是将图像指定为空div上的背景，并调整div的“padding-top”以获得所需的宽高比（例如：padding-top：56.25％;给出landscape'ish比率）。< / p>

以下是使用4个不同尺寸图像的示例小提琴：

<div class="portfolio-grid">

    <a href="#" class="portfolio-item">
        <div class="wrapper">
            <!-- DP Image as Background -->

            <div class="details">
                <h2>Item Heading</h2>
            </div>

        /* Control .portfolio-item's width on Various Screen Sizes */
        @media(max-width:767px) {
            width: 50%;
        }

        @media(max-width:479px) {

        /* ------ */
