在<h1>之后将填充应用于具有某些类的元素

Question

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<ul>),该<h1>元素具有一个被调用的类specialInstructionsNotes,用于将额外填充(30px)应用于仅具有类specialInstructionsNotes 的最后一个元素.

我试图结合使用:first-of-type和:nth-of-type(1)CSS3选择器,但这些选择器不会转移到IE8(这是我将要去的最低的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(将填充仅应用于类的最后一个元素specialInstructionsNotes).

注意:可以有3个或更多元素应用此类,只要具有类的最后一个元素.specialInstructionNotes在最底部具有填充.对不起任何困惑.

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.对于我遇到的一些页面/场景,这是我目前拥有的HTML.

这样的解决方法怎么样？

.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 */
}
