<div>顶部</div>上的未知额外空间

Question

我正在创建一个带有几个div的表madde，并且我在第一行（样式为head）和其余部分之间有一个额外的空间，只有前两列（div）。在这里你可以看到很清楚：

没有样式属性导致这个空间，至少我无法找到它的原因。

我已经在jsfiddle上复制了它，你可以看到它还设置了额外的空间：DEMO

这里我带来HTML＆amp; Syle相关代码：

HTML：

<div class="tableWrap">
<div class="tableHeader">
    <div class="contentColumn60">
        <span class="tableHeaderText">Turno</span>
    </div>
    <div class="contentColumn20">
        <span class="tableHeaderText">Tipo</span>
    </div>
    <div class="contentColumn10">
        <span class="tableHeaderText">Editar</span>
    </div>
    <div class="contentColumn10">
        <span class="tableHeaderText">Reactivar</span>
    </div>
</div>
<div class="tableContent">
    <div class="contentColumn60">
        <span class="tableContentText">Mañana(17:00 - 21:00)</span>
    </div>
    <div class="contentColumn20">
        <span class="tableContentText">Mañanas</span>
    </div>
    <div class="contentColumn10">
        <a href="#"><div class="editIcon"></div></a>
    </div>
    <div class="contentColumn10">
        <a href="#"><div class="discontinueIcon"></div></a>
    </div>
</div>
    <div class="tableContent">
    <div class="contentColumn60">
        <span class="tableContentText">Mañana(17:00 - 21:00)</span>
    </div>
    <div class="contentColumn20">

    <div class="contentColumn10">

    </div>
    <div class="contentColumn10">
        <a href="#"><div class="discontinueIcon"></div></a>
    </div>
</div>
    <div class="tableContent">
    <div class="contentColumn60">
        <span class="tableContentText">Mañana(17:00 - 21:00)</span>
    </div>
    <div class="contentColumn20">
        <span class="tableContentText">Mañanas</span>
    </div>
    <div class="contentColumn10">

    </div>
    <div class="contentColumn10">
        <a href="#"><div class="discontinueIcon"></div></a>
    </div>
</div>

Answer 1

由于元素为inline-block，您可以使用vertical-align:top根据需要对齐它们。值得注意的是，默认属性值为baseline;这就解释了为什么他们表现得像他们一样。 UPDATED EXAMPLE HERE

.contentColumn60 {
    height: 40px;
    width: 58%;
    border-top: 1px solid #fafafa;
    border-bottom: 1px solid #e0e0e0;
    border-left: 1px solid #e0e0e0;
    display: inline-block;
    vertical-align: top;
}

.contentColumn20 {
    height: 40px;
    width: 20%;
    border-top: 1px solid #fafafa;
    border-bottom: 1px solid #e0e0e0;
    border-left: 1px solid #e0e0e0;
    display: inline-block;
    vertical-align: top;
}

Answer 2

使用overflow:hidden;作为内容列60,20,10，它完美无缺

Answer 3

添加clearfix或使用vertical-align：top和overflow：hidden

.contentColumn60:after {
  content: "";
  display: table;
  clear: both;
}
