我想将没有id的td的宽度减为零。

或者有谁知道怎么去除ASP.NET的Menu控件生成的这些多余td元素 ?

Answer 1

ASP.NET doesn’t know CSS but it works
td {display:none}
td[id] {display:table-cell}

Answer 2

Use css priority to implement, and use different selectors to define the same element

Answer 3

http://www.w3school.com.cn/css/css_selector_descendant.asp,我想w3c是是回答你的最好方式，在这里不应该贴代码为具体的问题，这不适合啊

Answer 4

CSS3 has a not selector, for example:

p:not(#p1){
   ##css
}

is to select all p elements but exclude the p element with id p1
