Bootstrap 3.3.7 md 上的列布局问题

Question

这是我的引导网站的当前布局。不幸的是，它不起作用，因为列在 md 大小上完全关闭。

Here 是当前视图。

我的目标是让它们按 md 大小按 2 列分组。所以布局是image+text;new column;image+text;new column;image+text

        <div class="row">
            <div class="col-lg-4 col-md-6 coko">
                <img src="images/malinica.jpg" class="img-responsive img-rounded" alt="Cokol">
                <a class="link" href="#"><div class="preko">
                <h3 class="text-center">Cakes</h3></div></a> 
            </div>
            <div class="col-lg-4 col-md-6 coko">
                <p class="text-center">In 1995, <a href="index.html">The Rolling Pin</a> 
                opened its first location on a quiet street corner in the heart of 
                Munich. From its inception, The Rolling Pin has been cherished for its 
                classic Germany baked goods, vintage decor and warm, invitig atmosphere.

        </div>
        <div class="col-lg-4 col-md-6 coko">

            <p>If you have a dog or cat, this is the right place for

Answer 1

看看这是否有帮助： https://codepen.io/panchroma/pen/geYeep

这样的布局有两个挑战。

首先，您希望所有元素都在同一行中，其次，您需要允许列的高度不同。第 n 个子选择器和一些 @media 选择器是操纵 CSS 并使其工作的有效方式。

HTML - 这与您的完全相同，只是注释掉了几行，因此所有元素都在同一行中

 <div class="row">
  <div class="col-lg-4 col-md-6 coko">
    <img src="http://www.fillmurray.com/500/400" class="img-responsive img-rounded" alt="Cokol">
    <a class="link" href="#">
      <div class="preko">
        <h3 class="text-center">Cakes</h3>
      </div>
    </a>
  </div>
  <div class="col-lg-4 col-md-6 coko">
    <p class="text-center">In 1995, <a href="index.html">The Rolling Pin</a> opened its first location on a quiet street corner in the heart of Munich. From its inception, The Rolling Pin has been cherished for its classic Germany baked goods, vintage decor and warm, invitig
      atmosphere.
    </p>
  </div>
  <div class="col-lg-4 coko col-md-6">
    <img src="http://www.fillmurray.com/500/200" class="img-responsive img-rounded" alt="Coko">
    <a class="link" href="#">
      <div class="preko">
        <h3 class="text-center">Muffins</h3>
      </div>
    </a>
  </div>
  <!--         </div> -->
  <!--         <div class="row"> -->
  <div class="col-lg-4 coko col-md-6">
    <h3 class="text-center">We stand for organic</h3>
    <p class="text-center">The Rolling Pin has a whole line of organic desserts and drinks that prove that eating organic can taste just as delicious.
    </p>
  </div>
  <div class="col-lg-4 col-md-6 coko">
    <img src="http://www.fillmurray.com/500/300" class="img-responsive img-rounded" alt="Coko">
    <a class="link" href="#">
      <div class="preko">
        <h3 class="text-center">Drinks</h3>
      </div>
    </a>
  </div>
  <div class="col-lg-4 col-md-6 coko">
    <h3 class="text-center">Pet friendly</h3>
    <p>If you have a dog or cat, this is the right place for you. Except our place, we offer you a special menu for your pet.</p>

  </div>
</div>  

CSS - 第一个媒体查询确保每第三列向左浮动到 md 视口中新行的开头。

另一个是为了补偿在你的 HTML 中删除第二行 div

@media (max-width: 1199px) {
  .row div:nth-child(odd){
    clear:left
  }
}


@media (min-width: 1200px) {
  .row div:nth-child(3n + 4){
    clear:left
  }
}   

祝你好运！

Answer 2

这是因为min-height 的问题。添加额外的div 和min-height。

或

为您的.coko div 添加min-height。
