Introduction

Tailwind 4 is a popular utility-first CSS framework that provides a wide range of features to help developers create responsive and accessible web applications. One of the key features of Tailwind 4 is its color-scheme functionality, which allows developers to easily switch between different color schemes in their applications. However, some developers have reported issues with the color-scheme classes not working as expected, particularly when using classes with dashes in between. In this article, we will explore the issue and provide a solution to the problem.

The Issue

The issue arises when using classes with dashes in between, such as scheme-light-dark or scheme-only-dark. When these classes are used, the color-scheme functionality does not work as expected. This is because the dashes in the class names are causing the color-scheme classes to be interpreted incorrectly.

The Correct Usage

To fix this issue, we need to use the correct class names without dashes. For example, instead of using scheme-light-dark, we should use scheme-light dark. Similarly, instead of using scheme-only-dark, we should use scheme-only dark.

Example Use Cases

Here are some example use cases that demonstrate the correct usage of color-scheme classes:

Light and Dark Schemes: To switch between light and dark schemes, you can use the following classes:

``` * **Only Dark Scheme**: To use only the dark scheme, you can use the following class: ```html

``` * **Only Light Scheme**: To use only the light scheme, you can use the following class: ```html

``` **Conclusion** ----------

In conclusion, the issue with the color-scheme classes not working in Tailwind 4 is due to the dashes in the class names. To fix this issue, we need to use the correct class names without dashes. By following the examples provided in this article, you can easily switch between different color schemes in your Tailwind 4 applications.

Troubleshooting Tips

Here are some troubleshooting tips to help you resolve the issue:

Check the Class Names: Make sure that you are using the correct class names without dashes.
