How Can I Identify IE11 Exclusively Using CSS?

Identifying IE11 Exclusively Using CSS

While IE10 lacks browser detection tags, distinguishing it from its successor, IE11, presents a unique challenge. Assuming shared support for IE10 styles in IE11, it becomes necessary to identify any unique characteristics in IE11's CSS capabilities.

Using CSS Preprocessors

CSS preprocessors like Sass and Less offer conditional compilation based on factors such as browser versions. However, this method relies on user agent sniffing, which can be unreliable due to user manipulation or intentional browser stealth.

CSS Media Queries

Unfortunately, IE11 does not introduce any unique CSS properties or media features that set it apart from IE10. Therefore, using CSS media queries to specifically target IE11 is not feasible.

Browser Experiments

Some developers have attempted browser experiments to expose IE11's nuances, but these techniques are unreliable and not practical for widespread application.

Conclusion

While the detection of IE10 using JavaScript capability testing is viable, identifying IE11 exclusively through CSS remains elusive. CSS-based solutions are limited by the lack of unique properties or features in IE11, and other methods, such as user agent sniffing or browser experiments, are unreliable or impractical. In the absence of a definitive CSS solution, alternative approaches should be explored.
