SCSS引用元素的特定實例

Question

非常新的Scss/Sass在我的mod.scss文件的其他地方，編寫了我經常重複使用的樣式Ul > li。但是，在另一個mod.scss文件中，我需要爲單個特定實例更改此代碼。

是否有可能實質上創建一個if-like聲明：「如果UL/LI標籤出現在.content-section類別下，則採取行爲X，Y和z」？

.content-section 
{ 
    margin: 40px 0px; 

    & .siteTitleText 
    { 
     margin-bottom: 50px; 
    } 

    & .headers 
    { 
     margin-bottom: 30px; 
    } 

    img 
    { 
     margin: 30px 0px; 
    } 

    *ul* 

} 

HTML：

<div class="content-section vendors"> 
    <p class="headers">Modules, partials, and vendor</p> 
    <p class="bodyText">As you can see this divides my project into three basic types of files. Modules, partials, and vendored stylesheets.</p> 
    <ul> 
     <li class="bodyText">The modules directory is reserved for Sass code that doesn't cause Sass to actually output CSS. Things like mixin declarations, functions, and variables.</li> 

     <li class="bodyText">The partials directory is where the meat of my CSS is constructed. A lot of folks like to break their stylesheets into header, content, sidebar, and footer components (and a few others). As I'm more of a SMACSS guy myself, I like to break things down into much finer categories (typography, buttons, textboxes, selectboxes, etc…).</li> 

     <li class="bodyText"></li> 
    </ul> 
</div>

使用+在代碼中選擇關閉標籤下下一場比賽。 如果您想在.content-section內選擇子女標籤，只需簡單地嵌套標籤即可。

參考：w3 documentation

.content-section { 
    margin: 40px 0px; 

    & .siteTitleText { 
     margin-bottom: 50px; 
    } 

    & .headers { 
     margin-bottom: 30px; 
    } 

    img { 
     margin: 30px 0px; 
    } 

    ul, li { // If .content-section has a child named ul or li, do this: 
     margin: 100px; 
    } 
}
