最佳答案
是否可以使用CSS3选择器:first-of-type
来选择具有给定类名的第一个元素?我的测试不成功,所以我想这不是?
代码(http://jsfiddle.net/YWY4L/):
p:first-of-type {color:blue}
p.myclass1:first-of-type {color:red}
.myclass2:first-of-type {color:green}
<div>
<div>This text should appear as normal</div>
<p>This text should be blue.</p>
<p class="myclass1">This text should appear red.</p>
<p class="myclass2">This text should appear green.</p>
</div>
