我可以让 span 元素忽略列吗？

Question

我正在创建一个网络应用程序，其中用户将包含单词/短语的框拖到一个区域中。当用户将鼠标悬停在框上时，会显示一个带有单词定义的工具提示。当用户将框拖入区域时，我希望它们分为两列。但是，在使用列时，工具提示会在越过区域边缘时中断。有没有办法解决这个问题？

How tooltips are at the moment

How I would like them to be

#div1 {
  float: left;
  width: 328px;
  height: 400px;
  margin-left: 4px;
  padding: 10px;
  border: 1px solid black;
  border-radius: 6px;
  background-color: white;
  -webkit-columns: 2;
  -moz-columns: 2;
  columns: 2;
  -moz-column-fill: auto;
  column-fill: auto;
}

.box {
  height: 54px;
  width: 160px;
  text-align: center;
  background-color: white;
  color: purple;
  border: 1px solid black;
  border-radius: 4px;
  margin-bottom: 2px;
  position: relative;
  text-align: center;
}

.tooltiptext {
  visibility: hidden;
  width: 160px;
  background-color: purple;
  color: #fff;
  text-align: center;
  border-radius: 6px;
  padding: 5px 0;
  position: absolute;
  z-index: 1;
  top: 100%;
  left: 50%;
  margin-left: -80px;
}

.box:hover .tooltiptext {
  visibility: visible;
}

<div id="div1" ondrop="drop(event)" ondragover="allowDrop(event)">
  {% for c in cards1 %}
  <div id="drag{{c.id}}-{{c.carddata.position}}" class="box" draggable="true" ondragstart="drag(event)">
    <span class="tooltiptext">{{c.carddata.description}}</span>
    <div id="text{{c.id}}-{{c.carddata.position}}" class="text"><br>{{c.carddata.name}}</div>
  </div>
  {% endfor %}
</div>

Answer 1

如果您将.box 的display 重置为inline-block，它将不会跨越到下一列：

#div1 {
  float: left;
  width: 328px;
  height: 250px;
  margin-left: 4px;
  padding: 10px;
  border: 1px solid black;
  border-radius: 6px;
  background-color: white;
  -webkit-columns: 2;
  -moz-columns: 2;
  columns: 2;
  -moz-column-fill: auto;
  column-fill: auto;
}

.box {
display:inline-block;/* to keep in a single column */
  height: 54px;
  width: 160px;
  text-align: center;
  background-color: white;
  color: purple;
  border: 1px solid black;
  border-radius: 4px;
  margin-bottom: 2px;
  position: relative;
  text-align: center;
}

.tooltiptext {
  visibility: hidden;
  width: 160px;
  background-color: purple;
  color: #fff;
  text-align: center;
  border-radius: 6px;
  padding: 5px 0;
  position: absolute;
  z-index: 1;
  top: 100%;
  left: 50%;
  margin-left: -80px;
}

.box:hover .tooltiptext {
  visibility: visible;
}

<div id="div1">
  <div  class="box">
    <span class="tooltiptext">c.carddata.description c.carddata.description c.carddata.description c.carddata.description c.carddata.description</span>
    <div class="text">c.carddata.name<br/>c.carddata.name</div>
  </div>
  <div  class="box">
    <span class="tooltiptext">c.carddata.description c.carddata.description c.carddata.description c.carddata.description c.carddata.description</span>
    <div class="text">c.carddata.name<br/>c.carddata.name</div>
  </div>
  <div  class="box">
    <span class="tooltiptext">c.carddata.description c.carddata.description c.carddata.description c.carddata.description c.carddata.description</span>
    <div class="text">c.carddata.name<br/>c.carddata.name</div>
  </div>
  <div  class="box">
    <span class="tooltiptext">c.carddata.description c.carddata.description c.carddata.description c.carddata.description c.carddata.description</span>
    <div class="text">c.carddata.name<br/>c.carddata.name</div>
  </div>
  <div  class="box">
    <span class="tooltiptext">c.carddata.description c.carddata.description c.carddata.description c.carddata.description c.carddata.description</span>
    <div class="text">c.carddata.name<br/>c.carddata.name</div>
  </div>
  <div  class="box">
    <span class="tooltiptext">c.carddata.description c.carddata.description c.carddata.description c.carddata.description c.carddata.description</span>
    <div class="text">c.carddata.name<br/>c.carddata.name</div>
  </div>
  <div  class="box">
    <span class="tooltiptext">c.carddata.description c.carddata.description c.carddata.description c.carddata.description c.carddata.description</span>
    <div class="text">c.carddata.name<br/>c.carddata.name</div>
  </div>
</div>

由于您使用固定高度，您可能还需要考虑在父级上设置这些规则的 flex 方法

  display:flex;
  flex-flow:column wrap;

（列 CSS 仍处于实验状态，似乎不再进化）

#div1 {
  float: left;
  width: 328px;
  height: 250px;
  margin-left: 4px;
  padding: 10px;
  border: 1px solid black;
  border-radius: 6px;
  background-color: white;
   display:flex;
  flex-flow:column wrap; 
}

.box {
  height: 54px;
  width: 160px;
  margin:0 5px 0 0;
  text-align: center;
  background-color: white;
  color: purple;
  border: 1px solid black;
  border-radius: 4px;
  margin-bottom: 2px;
  position: relative;
  text-align: center;
}

.tooltiptext {
  visibility: hidden;
  width: 160px;
  background-color: purple;
  color: #fff;
  text-align: center;
  border-radius: 6px;
  padding: 5px 0;
  position: absolute;
  z-index: 1;
  top: 100%;
  left: 50%;
  margin-left: -80px;
}

.box:hover .tooltiptext {
  visibility: visible;
}

<div id="div1">
 
  <div  class="box">
    <span class="tooltiptext">c.carddata.description c.carddata.description c.carddata.description c.carddata.description c.carddata.description</span>
    <div class="text">c.carddata.name<br/>c.carddata.name</div>
