我想要做的是在 header1 元素之后的最后一个元素（例如段落<p>或无序列表），该元素具有一个类，该类被称为仅对具有类 specialInstructionsNotes的最后一个元素应用额外的填充（30px） 。<ul><h1>specialInstructionsNotes

我尝试合并使用:first-of-type和:nth-of-type(1)CSS3 选择器，但这些选择器并没有转移到 IE8（这是我要使用的最低 IE 兼容浏览器）。我的目标是能够在所有最新的浏览器和 IE8+ 中显示CSS 设置（即仅将填充应用于带有 class 的最后一个元素）。specialInstructionsNotes

注意：可以有 3 个或更多元素应用了这个类，只要这个类的最后一个元素.specialInstructionNotes在最底部有填充。很抱歉有任何混淆。

这是我到目前为止的完整 CSS：

.specialInstructionsNotes {
    color: #004abc;
    font-size: 1.1em;
    line-height: 26px;
    padding: 0 3%;
}    

h1 + p.specialInstructionsNotes + *, 
    h1 + ul.specialInstructionsNotes + *, 
    h1 + p.specialInstructionsNotes:nth-of-type(1), 
    h1 + ul.specialInstructionsNotes:nth-of-type(1) { 
        padding: 0 0 30px; 
    }

h1 + p.specialInstructionsNotes:first-of-type, 
h1 + ul.specialInstructionsNotes:first-of-type { 
    padding: 0; 
}

对于 HTML，元素位于一个 div 中，并且是 div 中包含的最顶层元素。这是我目前遇到的一些页面/场景的 HTML。

第 1 页：

这样的解决方法呢？

.specialInstructionsNotes {
   padding-bottom: 30px; /* set padding for all special elements */
}
.specialInstructionsNotes + .specialInstructionsNotes {
   margin-top: -30px; /* but make the next element hide the bottom padding
                         of its preceding siblings of the same class */
}

如果您需要您的解决方案在两次以上的情况下工作，.specialInstructionsNotes并且如果没有其他元素，您还希望在第一个元素上进行填充，那么即使您不喜欢它，js 解决方案也会派上用场；）

JS

$('h1').each(function() {
    $(this).nextAll('.specialInstructionsNotes:last').addClass('last-note');
});

然后很容易解决 CSS 中的问题：

CSS

.specialInstructionsNotes.last-note {
    padding: 0 0 30px; 
}

将它们添加到您的<head>部分：

使用CSS（脏但有效！）：

<!--[if lte IE 8]>
<style type="text/css">
    .main .specialInstructionsNotes{
        padding-bottom: expression(this.nextSibling==null?'30px':'3%');
    }
</style>
<![endif]-->

您还可以创建一个ie.css包含上面的 CSS 并像这样调用它：

<!--[if lte IE 8]>
    <link rel="stylesheet" href="ie.css" type="text/css" />
<![endif]-->

与jQuery：

<!--[if lte IE 8]>
    <script type="text/javascript">
        $(function(){
            $(".main :last-child.specialInstructionsNotes").css("padding-bottom", "30px dashed red");
        });
    </script>
<![endif]-->
