Nth Child() in IE8: A Comprehensive Guide to Zebra Striped Tables
Zebra striping tables is a common technique to improve readability by alternating the background colors of odd and even rows. While modern browsers support the nth child() CSS element for this purpose, Internet Explorer 8 (IE8) does not natively. This article explores strategies to emulate nth child() in IE8, enabling you to achieve visually appealing tables in all browsers.
Polyfill Approach: Selectivizr
One solution is to use a polyfill such as Selectivizr. Polyfills are scripts that extend browser capabilities and mimic features not supported natively. Selectivizr, specifically, provides extended support for various CSS selectors, including nth child(). By incorporating Selectivizr into your project, you can utilize nth child() and achieve zebra striping in IE8.
Native IE8 Emulation
While polyfills offer a straightforward solution, you may opt for a more native approach that leverages IE8's existing first-child selector. This technique involves a clever trick to mimic nth child() behavior:
/*li:nth-child(2)*/ li:first-child + li {}/*Works for IE8*/
In this example, we target the element directly following the first child element, which effectively simulates the effect of selecting the second child. This method works for simple nth child() selectors like nth-child(2) or nth-child(odd), where the offset is known and constant.
Limitations
While this technique provides a good approximation of nth child() for basic scenarios, it has some limitations. Complex selectors like nth-child(2n 1) or nth-child(odd), which rely on a variable offset, cannot be fully emulated in IE8. Additionally, some CSS frameworks may not be compatible with this approach, as they may rely on more advanced nth child() selectors.
Conclusion
By understanding the capabilities and limitations of IE8, you can achieve zebra striping in your tables using nth child() emulation. Whether you choose to employ a polyfill like Selectivizr or implement the native emulation technique, you can enhance the visual appeal of your tables and ensure compatibility across all major browsers.
