这类似于这个问题在这里，但略有不同。

我想在移动设备上重新排序三个div，并将它们并排放置在台式机上。请参阅所附图片以获得所需结果：

我在描述此过程时遇到了很多麻烦，希望图片对您有所帮助！

编辑：这是通过复制代码工作的代码片段：

const Main = () => (

<section className="" id="section-2">

      <div className="container">

        <div className="row">

          <div className="col-12 d-md-none">

            <div className="text-center">

              <span className="text-uppercase small-text small-text--lighter">step 2</span>

            </div>

            <div className="text-center">

              <h2 className="text-center">HEADER 2</h2>

            </div>

          </div>

          <div className="col-12 col-md-6">

            <img alt="tbd" src="http://www.pixedelic.com/themes/geode/demo/wp-content/uploads/sites/4/2014/04/placeholder4.png" />

          </div>

          <div className="col-12 col-md-5 offset-md-1 text-center text-md-left">

            <div className="d-flex flex-column justify-content-between align-items-center align-items-md-start">

              <div className="d-none d-md-block">

                <span className="text-uppercase small-text small-text--lighter">step 2</span>

              </div>

              <div className="d-none d-md-block">

                <h2 className="">HEADER 2</h2>

              </div>

              <div>

                <p>SOME PARAGRAPH TEXT</p>

              </div>

            </div>

          </div>

        </div>

      </div>

    </section>

)

ReactDOM.render(

  <Main />,

  document.getElementById("react")

);


img {

  height: auto;

  width: 100%;

}
