CSS class and id with the same name
提问by Spencer
Is there anything wrong with having a css class and id with the same name? Like .footer for the article/post's footer and #footer for the page footer.
使用同名的 css 类和 id 有什么问题吗？像 .footer 表示文章/帖子的页脚，#footer 表示页面页脚。

Nope, perfectly acceptable.
不，完全可以接受。
A class is defined using a .and an ID is defined using a #. So as far as the browser is concerned, they're two totally separate items.
类使用 定义.，ID 使用 定义#。所以就浏览器而言，它们是两个完全独立的项目。
The only thing to be careful of is generating any confusion for yourself. It's probably best practise to keep the names different purely for code readability, but there's no harm in them being the same.
唯一要小心的是给自己带来任何混乱。纯粹为了代码可读性而保持名称不同可能是最佳实践，但它们相同也没有坏处。

No, there is nothing wrong, but it might be better to use different names to not confuse other developers. It is more (human) error prone to use different names.
不，没有错，但最好使用不同的名称以免混淆其他开发人员。使用不同的名称更容易（人为）错误。

是的，您可以对id和class使用相同的名称，因为这两个参数都有自己的意义。谢谢

The only problem with having same name for class and id is code readability and maintainability. They can have the same names, the browser will render the correct CSS as classes and ids are marked differently (. for class and # for id), but an upgrade or bug fix can be a problem for the developer.
class 和 id 具有相同名称的唯一问题是代码可读性和可维护性。它们可以具有相同的名称，浏览器将呈现正确的 CSS，因为类和 id 的标记不同（. 表示 class 和 # 表示 id），但升级或错误修复对开发人员来说可能是一个问题。
