提问by nkcmr
I'm creating a tumblr them and I have to write an external CSS file but I am having trouble editing the css style of the post elements.

This its structure:
这是它的结构：
<li class="post quote">
{other code}
</li>
The problem is that the class name has a space in it.
How would I create a CSS class to access this? And yes, I know I can just put a style attribute in the element tag but I was kind of hoping for another option.

This is not possible in CSS. What you are doing is giving the element twoclasses.
这在 CSS 中是不可能的。你正在做的是给元素两个类。
You can address them such:
你可以这样称呼他们：
.post.quote { .... }
but in your case, it's probably better to use a valid separator like
但在您的情况下，最好使用有效的分隔符，例如
post_quote

This element actually has twoclasses - it is marked with both the postclass andthe quoteclass. So, you can use the following selectors to access it:
这个元素实际上有2类-它标有两个post类和的quote类。因此，您可以使用以下选择器来访问它：
// css
.post { ... } // elements with the post class
.quote { ... } // elements with the quote class
// jQuery
var postLis = $('.post');
var quoteLis = $('.quote');
You can also stack selectors to return all elements which meet all conditions in the selector, by including the different selectors together:
您还可以通过将不同的选择器包含在一起来堆叠选择器以返回满足选择器中所有条件的所有元素：
// css
.post.quote { ... } // elements with both the post and quote classes
// jQuery
var postAndQuoteLis = $('.post.quote');

This might work:
这可能有效：
$('li').each(function() {
if($(this).attr('class').indexOf(" ")>-1) {
$(this).css('border','1px solid #ff0000')
}
}
