我想为中小型设备展示不同的卡片视图。我需要根据容器的宽度更改卡片样式。对于大型设备，我有这种卡片样式：
<div class="col-lg-3 col-md-4 col-sm-6 portfolio-item">
<div class="card h-100">
<a href="#"><img class="card-img-top" src="http://placehold.it/700x400" alt=""></a>
<div class="card-body">
<h4 class="card-title">
<a href="#">Project One</a>
</h4>
<p class="card-text">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Amet numquam aspernatur eum quasi sapiente nesciunt? Voluptatibus sit, repellat sequi itaque deserunt, dolores in, nesciunt, illum tempora ex quae? Nihil, dolorem!</p>
</div>
</div>
</div>
对于中小型设备，我需要这个：
<div class="row">
<div class="col-md-7">
<a href="#">
<img class="img-fluid rounded mb-3 mb-md-0" src="http://placehold.it/700x300" alt="">
</a>
</div>
<div class="col-md-5">
<h3>Project One</h3>
<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Laudantium veniam exercitationem expedita laborum at voluptate. Labore, voluptates totam at aut nemo deserunt rem magni pariatur quos perspiciatis atque eveniet unde.</p>
<a class="btn btn-primary" href="#">View Project</a>
</div>
</div>
我不知道该怎么做。有人可以建议实现这一目标的最佳/最优化方式吗？
