Bulma - 为什么所有列都在一行？

Question

当我使用v-for时，我将Bulma与VueJS一起使用，所有列都在一行上，我尝试添加is-4，然后列宽会更改，但它们仍然在一行

<div class='columns'>
<div class='column' 
v-for='item in weatherData.list' 
v-bind:key='item.data'>

<div class="card">
  <div class="card-image">
    <figure class="image is-4by3">
      <img src="https://bulma.io/images/placeholders/1280x960.png" alt="Placeholder image">
     </figure>
    </div>
   <div class="card-content">
               ...
    </div>
   </div>
   </div>
   </div>

任何人都可以向我解释它是如何运作的吗？

谢谢！

如果要包装列，则需要将.is-multiline修饰符添加到.columns类。 More information here
