Body标签上的类或ID [英] Class or ID on Body Tag
问题描述
我一直在将HTML文档的正文标签使用ID 允许更大的CSS控制（＃9）。最近，虽然发生了，我可以做完全相同的事情通过应用一个类的身体标签。我想知道每个选择的积极和消极。如果我有多个页面，其中body标签具有相同的ID，是否最好使用类？你怎么看？为什么？
I've been applying an ID to the body tag of my HTML documents lately to allow greater CSS control (#9). Recently the though occurred to me that I could do exactly the same thing by applying a class to the body tag. I want to know positives and negatives of each choice. If I have multiple pages where the body tag has the same ID, is it better to use a class? What do you think? Why?
