将样式应用于CSS中的列表

Question

I have a list:

<li> one </li> <li> two </li> <li> three </li> how can i call out a specific element in the list to apply a style to? for example: how can i call "two" can apply a style to it.

Answer 1

用于无序列表的第二个元素的CSS选择器将是

ul>li:nth-child(2)

Answer 2

You are probably looking for eq()

$('li').eq(0) 

to get the first element

Answer 3

$('li:eq(1)'); is the jQuery selector for the second element (note: zero based index). If you want to use a variable for the element number, then use something like @Soufiane $('li').eq(num);

in CSS you can try li + li and you'll get IE7+ support.
