我正在尝试更改div内奇数div的样式。由于某些原因，nth-of-type(odd)位于另一个div内时会影响我的所有div。这是我的常规div和奇数div的代码：




 .video-entry-summary {
  width: 214px;
  height: 210px;
  margin-left: 10px;
  float: left;
  position: relative;
  overflow: hidden;
  border: 1px solid black;
}

.video-entry-summary:nth-of-type(odd) {
  width: 214px;
  height: 210px;
  margin-left: 0px;
  float: left;
  position: relative;
  overflow: hidden;
  border: 1px solid black;
  background: #ccc;
} 

 <div id="post-501" class="post-501 post type-post status-publish format-standard hentry category-moto-dz-films tag-news-sub-2">
  <div class="video-entry-summary">
    video 1
  </div>
</div>

<div id="post-240" class="post-240 post type-post status-publish format-standard hentry category-videos">
  <div class="video-entry-summary">
    video 2
  </div>
</div>

<div id="post-232" class="post-232 post type-post status-publish format-standard hentry category-videos">
  <div class="video-entry-summary">
    video 3
  </div>
</div>

<div id="post-223" class="post-223 post type-post status-publish format-standard hentry category-videos">
  <div class="video-entry-summary">
    video 4
  </div>
</div>





由于某些原因，nth-of-type在div内包裹时不起作用，但是在没有包裹在div中时起作用。 >不在div内时的工作版本：




 .video-entry-summary {
  width: 214px;
  height: 210px;
  margin-left: 10px;
  float: left;
  position: relative;
  overflow: hidden;
  border: 1px solid black;
}

.video-entry-summary:nth-of-type(odd) {
  width: 214px;
  height: 210px;
  margin-left: 0px;
  float: left;
  position: relative;
  overflow: hidden;
  border: 1px solid black;
  background: #ccc;
} 

 <div class="video-entry-summary">
  video 1
</div>

<div class="video-entry-summary">
  video 2
</div>

<div class="video-entry-summary">
  video 3
</div>

<div class="video-entry-summary">
  video 4
</div>





如何使初始代码与上述代码相同？

:nth-of-type()与:nth-child()类似，因为它们必须全部来自同一父级。如果需要这些包装器div，请在这些包装器上使用:nth-of-type()： ：

div.post:nth-of-type(odd) .video-entry-summary {
    width:214px; 
    height:210px; 
    margin-left:0px;
    float:left;
    position:relative; 
    overflow:hidden; 
    border:1px solid black; 
    background:#ccc; 
}






 .post 

 :nth-child()
