<p>I don't think it is possible with pure css.</p>

<p>A very good reply to the same issue can be found here: <a href="https://stackoverflow.com/questions/5545649/can-i-combine-nth-child-or-nth-of-type-with-an-arbitrary-selector">Can I combine :nth-child() or :nth-of-type() with an arbitrary selector?</a></p>

<p>What I recommend is: add a new class to each odd element and style that one accordingly.</p>

<p>So you will have </p>

<pre><code>.comment
.event
.comment.odd
.event.odd
.event
.event.odd
.comment 
</code></pre>

<p>Etc</p>

<p>Otherwise, you can do it using js. But the extra class method should be good enough.</p>


blocks|key|4656570|text|您试图用一个非分层的HTML结构来表示本质上是分层的数据。nth-child指子对象在其父对象中的顺序，而不是在具有某个共享类的所有子对象中的顺序。所以基本上，你不能在CSS中做到这一点。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4656571|如果可以的话，试着这样组织HTML：|4656572|<div>

++<div+class="event">

++</div>

++<div+class="event">
++++<div+class="comment"></div>
++++<div+class="comment"></div>
++++<div+class="comment"></div>
++</div>

++<div+class="event">
++</div>

</div>|code-block|syntax|javascript|4656573|现在，您可以使用以下命令设置样式|4656574|.event:nth-child(odd)++++{+color:+white;+}
.event:nth-child(even)+++{+color:+black;+}
.comment:nth-child(odd)++{+color:+white;+}
.comment:nth-child(even)+{+color:+black;+}|4656575|由于您似乎希望注释的开头颜色与它所在的活动的颜色相同，因此需要这样做：|4656576|.event:nth-child(odd)+{+color:+white;+}
.event:nth-child(odd)+.comment:nth-child(odd)+{+color:+white;+}
.event:nth-child(odd)+.comment:nth-child(even)+{+color:+black;+}

.event:nth-child(even)+{+color:+black;+}
.event:nth-child(even)+.comment:nth-child(odd)+{+color:+black;+}
.event:nth-child(even)+.comment:nth-child(even)+{+color:+white;+}|4656577|上面使用的是div元素。但是，如果您真的想对表执行此操作，可以尝试使用以下HTML，然后使用与上面相同的逻辑：|4656578|<table>

++<thead><tr><td>Event</td></tr></thead>
++<tbody>
++++<tr><td>Comment</td></tr>
++</tbody>

++<thead+<tr><td>Event</td></tr></thead>
++<tbody>
++++<tr><td>Comment</td></tr>
++++<tr><td>Comment</td></tr>
++++<tr><td>Comment</td></tr>
++</tbody>

++<thead><tr><td>Event</td></tr></thead>

</table>|4656579|然后写下：|4656580|thead:nth-of-type(odd)+{+color:+white;+}
tbody:nth-of-type(even)+tr:nth-child(odd)+{+color:+white;+}

<p>You are trying to represent what is essentially hierarchical data with a non-hierarchical HTML structure. <code>nth-child</code> refers to the order of the child within its parent, not within all children with some shared class. So basically, you can't do this in CSS. </p>

<p>Try structuring your HTML like this if you can:</p>

<pre><code>&lt;div&gt;

  &lt;div class="event"&gt;
    &lt;div class="comment"&gt;&lt;/div&gt;
  &lt;/div&gt;

  &lt;div class="event"&gt;
    &lt;div class="comment"&gt;&lt;/div&gt;
    &lt;div class="comment"&gt;&lt;/div&gt;
    &lt;div class="comment"&gt;&lt;/div&gt;
  &lt;/div&gt;

  &lt;div class="event"&gt;
  &lt;/div&gt;

&lt;/div&gt;
</code></pre>

<p>Now you can style this with</p>

<pre><code>.event:nth-child(odd)    { color: white; }
.event:nth-child(even)   { color: black; }
.comment:nth-child(odd)  { color: white; }
.comment:nth-child(even) { color: black; }
</code></pre>

<p>Since you seem to want to start the comments with the same color as the event it is part of, you would need to do:</p>

<pre><code>.event:nth-child(odd) { color: white; }
.event:nth-child(odd) .comment:nth-child(odd) { color: white; }
.event:nth-child(odd) .comment:nth-child(even) { color: black; }

.event:nth-child(even) { color: black; }
.event:nth-child(even) .comment:nth-child(odd) { color: black; }
.event:nth-child(even) .comment:nth-child(even) { color: white; }
</code></pre>

<p>The above uses <code>div</code> elements. But if you really want to do this with a table, you could try using the following HTML, then use the same kind of logic as above:</p>

<pre><code>&lt;table&gt;

  &lt;thead&gt;&lt;tr&gt;&lt;td&gt;Event&lt;/td&gt;&lt;/tr&gt;&lt;/thead&gt;
  &lt;tbody&gt;
    &lt;tr&gt;&lt;td&gt;Comment&lt;/td&gt;&lt;/tr&gt;
  &lt;/tbody&gt;

  &lt;thead &lt;tr&gt;&lt;td&gt;Event&lt;/td&gt;&lt;/tr&gt;&lt;/thead&gt;
  &lt;tbody&gt;
    &lt;tr&gt;&lt;td&gt;Comment&lt;/td&gt;&lt;/tr&gt;
    &lt;tr&gt;&lt;td&gt;Comment&lt;/td&gt;&lt;/tr&gt;
    &lt;tr&gt;&lt;td&gt;Comment&lt;/td&gt;&lt;/tr&gt;
  &lt;/tbody&gt;

  &lt;thead&gt;&lt;tr&gt;&lt;td&gt;Event&lt;/td&gt;&lt;/tr&gt;&lt;/thead&gt;

&lt;/table&gt;
</code></pre>

<p>Then write:</p>

<pre><code>thead:nth-of-type(odd) { color: white; }
tbody:nth-of-type(even) tr:nth-child(odd) { color: white; }
tbody:nth-of-type(odd)  tr:nth-child(event) { color: black; }

thead:nth-of-type(even) { color: black; }
tbody:nth-of-type(even) tr:nth-child(odd) { color: black; }
tbody:nth-of-type(odd)  tr:nth-child(event) { color: white; }
</code></pre>

<p>It is impossible with pure CSS, you will have to use jQuery to add a class (or the style directly if you wish).</p>

<p>jQuery's indexing starts a 0, so what it considers even, we consider odd.</p>

<p>I have a table with 50 entries, some of which have a class of 'event' or 'comment.'  Here is what the table row entries look like:</p>

<p>Event, Comment, Event, Comment, Comment, Comment, Event</p>

<p>What I want to do is alternate the row colors of both the 'event' and 'comment' class names separately.  Currently what I have is this:</p>

<pre><code>tr.event:nth-child(odd) {
    background-color: #000;
}
tr.comment:nth-child(odd) {
    background-color: #000;
}
</code></pre>

<p>With this code, I get an output of: </p>

<p>Black (event), White (comment), Black (event), White (comment), Black (comment), White (comment), Black (event)</p>

<p>I want the output to be this:</p>

<p>Black (event), Black (comment), White (event), White (comment), Black (comment), White (comment), Black (event)</p>

<p>Any help would be great! </p>
