How to Style Elements with :nth-child and :before in IE8?

Browser Compatibility Limitations for :nth-child and :before in IE8

Internet Explorer 8 (IE8) presents a unique challenge when it comes to implementing CSS pseudo-elements like :nth-child and :before. While these selectors are widely supported in modern browsers, theyEXHIBIT limitations in IE8.

One such issue arises when using :nth-child to style specific elements within a list. As demonstrated by the CSS snippet, the selector #nav-primary ul li:nth-child(1) a:after applies styles to the after pseudo-element of the first list item's anchor tag. However, this selector fails to function correctly in IE8.

Alternative Approach Using Adjacent Sibling Combinator

To circumvent this limitation, one can employ the adjacent sibling combinator ( ) along with the first-child pseudo-class. This approach effectively achieves the same result by targeting subsequent siblings of the first child using the following CSS structure:

#nav-primary ul li:first-child a { ... }
#nav-primary ul li:first-child + li a { ... }
#nav-primary ul li:first-child + li + li a { ... }

This method effectively emulates the behavior of :nth-child(1), :nth-child(2), and so on. However, it has the drawback of not supporting more complex variations of :nth-child() like :nth-child(odd) or :nth-child(4n 3).
