<div class="commentList">
<article class="comment " id="com21"></article>
<article class="comment " id="com20"></article>
<article class="comment " id="com19"></article>
<div class="something"> hello </div>
</div>
I want to select #com19 ?
.comment {
width:470px;
border-bottom:1px dotted #f0f0f0;
margin-bottom:10px;
}
.comment:last-child {
border-bottom:none;
margin-bottom:0;
}
That does not work as long as I do have another div.something as actual last child in the commentList. Is it possible to use the last-child selector in this case to select the last appearance of article.comment?

If you are floating the elements you can reverse the order
i.e. float: right; instead of float: left;
And then use this method to select the first-child of a class.
/* 1: Apply style to ALL instances */
#header .some-class {
padding-right: 0;
}
/* 2: Remove style from ALL instances except FIRST instance */
#header .some-class~.some-class {
padding-right: 20px;
}
This is actually applying the class to the LAST instance only because it's now in reversed order.
Here is a working example for you:
<!doctype html>
<head><title>CSS Test</title>
<style type="text/css">
.some-class { margin: 0; padding: 0 20px; list-style-type: square; }
.lfloat { float: left; display: block; }
.rfloat { float: right; display: block; }
/* apply style to last instance only */
#header .some-class {
border: 1px solid red;
padding-right: 0;
}
#header .some-class~.some-class {
border: 0;
padding-right: 20px;
}
</style>
</head>
<body>
<div id="header">
<img src="some_image" title="Logo" class="lfloat no-border"/>
<ul class="some-class rfloat">
<li>List 1-1</li>
<li>List 1-2</li>
<li>List 1-3</li>
</ul>
<ul class="some-class rfloat">
<li>List 2-1</li>
<li>List 2-2</li>
<li>List 2-3</li>
</ul>
<ul class="some-class rfloat">
<li>List 3-1</li>
<li>List 3-2</li>
<li>List 3-3</li>
</ul>
<img src="some_other_img" title="Icon" class="rfloat no-border"/>
</div>
</body>
</html>
Something that I think should be commented here that worked for me:
Use :last-child multiple times in the places needed so that it always gets the last of the last.
Take this for example:
.page.one .page-container .comment:last-child {_x000D_
color: red;_x000D_
}_x000D_
.page.two .page-container:last-child .comment:last-child {_x000D_
color: blue;_x000D_
}<p> When you use .comment:last-child </p>_x000D_
<p> you only get the last comment in both parents </p>_x000D_
_x000D_
<div class="page one">_x000D_
<div class="page-container">_x000D_
<p class="comment"> Something </p>_x000D_
<p class="comment"> Something </p>_x000D_
</div>_x000D_
_x000D_
<div class="page-container">_x000D_
<p class="comment"> Something </p>_x000D_
<p class="comment"> Something </p>_x000D_
</div>_x000D_
</div>_x000D_
_x000D_
<p> When you use .page-container:last-child .comment:last-child </p>_x000D_
<p> you get the last page-container's, last comment </p>_x000D_
_x000D_
<div class="page two">_x000D_
<div class="page-container">_x000D_
<p class="comment"> Something </p>_x000D_
<p class="comment"> Something </p>_x000D_
</div>_x000D_
_x000D_
<div class="page-container">_x000D_
<p class="comment"> Something </p>_x000D_
<p class="comment"> Something </p>_x000D_
</div>_x000D_
</div>What about this solution?
div.commentList > article.comment:not(:last-child):last-of-type
{
color:red; /*or whatever...*/
}
I guess that the most correct answer is: Use :nth-child (or, in this specific case, its counterpart :nth-last-child). Most only know this selector by its first argument to grab a range of items based on a calculation with n, but it can also take a second argument "of [any CSS selector]".
Your scenario could be solved with this selector: .commentList .comment:nth-last-child(1 of .comment)
But being technically correct doesn't mean you can use it, though, because this selector is as of now only implemented in Safari.
For further reading:
if the last element type is article too, last-of-type will not work as expected.
maybe i not really understand how it work.
