How Can You Use nth-child() in Internet Explorer 8?

Overcoming Internet Explorer 8's Lack of nth-child() CSS Support

In CSS, the nth-child() element selector allows you to target specific child elements within a parent element. However, this selector is not supported in Internet Explorer 8 (IE8). This can be a challenge when you want to achieve effects like zebra striping in tables.

Solution

There are two main approaches to解决 this issue:

1. Use a Polyfill

Polyfills are scripts that add missing features to browsers. For CSS, Selectivizr is a popular polyfill that supports nth-child() in IE8.

2. Trick IE8 with First-child

Since IE8 supports the first-child selector, you can use it to create a workaround for nth-child():

/* li:nth-child(2) */
li:first-child + li { /* Works for IE8 */ }

This method will trick IE8 into selecting the second child element. However, it has limitations and cannot emulate more complex nth-child() selectors like nth-child(2n 1) or nth-child(odd).
