Prerequisites

Before we dive into the feature request, it's essential to ensure that you have read and agreed to the Contributing Guidelines and Code of Conduct. Additionally, please make sure to search for existing issues that already include this feature request, without success.

Describe the Feature Request

In the current implementation of Stencil, we can only add one global CSS file. However, with the increasing demand for customization and flexibility, it's essential to support multiple global styles. This feature request aims to enable users to pass a single or multiple global styles to Stencil, allowing for more extensive customization options.

Benefits of Multiple Global Styles

Supporting multiple global styles will provide several benefits, including:

Increased flexibility: Users will be able to customize their application's appearance by applying different styles to different components or sections of the application.
Improved maintainability: With multiple global styles, developers can easily switch between different styles without having to modify the underlying code.
Enhanced user experience: By providing users with more customization options, developers can create a more engaging and personalized experience.

Describe the Use Case

One of the primary use cases for this feature is to output one CSS file per theme. This is particularly useful in scenarios where multiple themes are required, and each theme has its unique set of styles. By supporting multiple global styles, developers can easily create and manage different themes, making it easier to switch between them.

Example Use Case

Suppose we have an e-commerce application that requires multiple themes, each with its unique set of styles. With the current implementation, we would need to create separate CSS files for each theme, which can lead to code duplication and maintenance issues. However, with the support for multiple global styles, we can create a single CSS file that includes all the styles for each theme, making it easier to manage and maintain.

Describe Preferred Solution

To implement this feature, we can modify the Stencil compiler to accept an array of global styles instead of a single style. This will allow users to pass multiple styles to the compiler, which will then be merged into a single CSS file.

Implementation Details

To implement this feature, we will need to make the following changes:

Modify the Stencil compiler to accept an array of global styles.
Update the compiler to merge the styles into a single CSS file.
Add support for multiple global styles in the Stencil configuration file.

Describe Alternatives

While there are no direct alternatives to this feature, we can consider the following options:

Use a separate CSS file for each theme: This approach requires creating separate CSS files for each theme, which can lead to code duplication and maintenance issues.
Use a CSS preprocessor: CSS preprocessors like Sass or Less can help manage multiple styles, but they may not provide the same level of flexibility as supporting multiple global styles in Stencil.

Related Code

The related code for this feature includes:

Stencil compiler: The Stencil compiler will need to be modified to accept an array of global styles.
Stencil configuration file: The Stencil configuration file will need to be updated to support multiple global styles.
CSS file: The CSS file will need to be updated to include all the styles for each theme.

Additional Information

To implement this feature, we will need to consider the following additional information:

Performance implications: Supporting multiple global styles may have performance implications, such as increased compilation time or larger CSS files.
Compatibility issues: We will need to ensure that the feature is compatible with existing Stencil applications and does not break any existing functionality.
Documentation updates: We will need to update the Stencil documentation to reflect the new feature and provide guidance on how to use it.
