Question

我正在创建一个页面，其中包含固定的导航栏，全屏背景和中间的文本。我不知道如何在横向模式下使其响应。在其他版本上，它的行为正常，但在横向上，因为我认为高度要小得多，所以文本与导航栏重叠。它看起来非常混乱。

我现在的代码中有什么东西可以改变来解决这个问题，但仍然保留全屏div吗？我到处都看，但没有什么工作。

到目前为止，这是我的代码：

.hero {
  height: 100vh;
  width: 100%;
  background: url('http://lorempixel.com/1200/600/') no-repeat;
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;
  position: relative;
}

.headline {
  position: absolute;
  top: 50%;
  left: 0%;
  right: 0;
  transform: translate(0%, -50%);
  -webkit-transform: translate(0%, -50%);
}

.headline h2 {
  font-weight: 100;
  font-size: 48px;
  color: #212121;
  margin-bottom: 10px;
}

        <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
      </form>
    </div>
  </nav>


  <div class="headline text-center">
    <div>
      <h2>Lorem ipsum dolor sit amet, consectetur adipiscing elit. <br>Morbi in volutpat diam, ut laoreet magna. </h2>
      <a class="btn btn-primary rounded-0" href="#">LINK ONE</a>
      <a class="btn btn-secondary rounded-0" href="#" target="_blank">LINK TWO</a>
    </div>
  </div>
  <!-- /.headline -->
</div>








<div style="height:900px"></div>
