How to Implement Flexbox in IE9 and Below?

Flexbox Alternative for IE9 and Below

When supporting older browsers like IE9, developers often face challenges with implementing modern CSS features like Flexbox. This article explores an alternative implementation to maintain consistency across multiple browsers.

Understanding Flexbox Support

Flexbox, a CSS layout module, offers flexibility in aligning and distributing elements. However, it's not supported by IE9 and below.

Fallback Approach with Modernizr

One approach to address this lack of Flexbox support is to use Modernizr, a JavaScript library that detects browser capabilities. Modernizr adds classes to the HTML element indicating whether Flexbox is supported or not. This allows developers to apply fallback styles based on these classes.

Example Implementation

Consider the following Flexbox implementation:

.container {
    display: flex;
}

In browsers that lack Flexbox support (e.g., IE9), the following fallback style can be added:

.no-flexbox .container {
    display: table-cell;
}

Additional Tips

• Inline-block can be used to simulate Flexbox horizontal spacing.
• Table-cell can be used to pin elements without Flexbox.
• Browser support for Flexbox is generally good from IE10 onwards.
• Using Autoprefixer and Modernizr can streamline the process of handling browser prefixes and providing fallbacks.

Conclusion

By utilizing Modernizr and leveraging fallback techniques, developers can achieve a consistent layout experience across browsers, including those that do not support Flexbox.
