CSS - 目标div的最后一个实例

Question

我有一个如下所示的div结构，我只想在页面上定位最后一个.pcontain，这样我就可以删除边框了 - 我该怎么办呢？

<div class="container">
    <div class="postcontainer">
        <div class="latest-posts">
            <div class="thumbnail"></div>
            <div class="pcontain"></div>
            <div class="more"></div>
        </div>
    </div>
    <div class="postcontainer">
        <div class="latest-posts">
            <div class="thumbnail"></div>
            <div class="pcontain"></div>
            <div class="more"></div>
        </div>
    </div>
    <div class="postcontainer">
        <div class="latest-posts">
            <div class="thumbnail"></div>
            <div class="pcontain"></div>

        </div>
    </div>
