A Framework for Evaluating Browser Support

The article discusses a framework for evaluating browser support for CSS features, particularly focusing on the implications of using new features with varying levels of support. As of November 2024, container queries are supported by approximately 93% of users, which raises questions about whether this level of support is adequate for production use. The author emphasizes the importance of considering the fallback experience for users with unsupported browsers. For instance, features like `text-wrap: pretty` can be used even with low support since they enhance the experience without detriment, while others like `overflow: clip` may lead to usability issues if not supported. The article also highlights the significance of understanding the specific audience's browser usage, as global statistics may not reflect the actual user base. Developers are encouraged to simulate unsupported browsers to assess fallback experiences and to provide alternative styles when necessary. Ultimately, the decision to use a CSS feature should consider the potential harm to users with unsupported browsers, especially in contexts where accessibility is critical.
