我对不要在 CSS 中使用 ID 选择器"这一行感到震惊.这是真的吗?我发现很多帖子都写过这个.

I was shocked by this line "Don't use ID selectors in CSS". Is it true? I found many posts have written this.

我认为我们可以将 ID 用于选择器.

I think we can use the ID for the selectors.

我还是想澄清一下.

推荐答案

Id 选择器优先于其他类型的选择器.这会使使用不太具体的选择器添加新规则变得更加困难，从而导致特异性战争:http://www.stuffandnonsense.co.uk/archives/css_specificity_wars.html

Id selectors have priority over other kinds of selectors. This can make it harder to add new rules using less specific selectors, leading to specificity wars: http://www.stuffandnonsense.co.uk/archives/css_specificity_wars.html
