What is the best method to apply a lightweight CSS framework across multiple Sitefinity projects?

Applying a lightweight CSS framework across multiple Sitefinity projects can be effectively achieved by creating a Frontend Package that includes a layout file. This approach allows you to centralize your CSS framework within a single package, ensuring consistent styling across all projects that utilize this package.

By creating a Frontend Package, you can encapsulate not only the CSS framework but also any associated assets, such as JavaScript files, layout templates, and other resources needed for the framework to function correctly. This method facilitates easier updates and maintenance since you only need to manage one package rather than updating each individual project separately. Additionally, it streamlines the integration process, reducing redundancy and potential discrepancies in styling between different Sitefinity applications.

In contrast, incorporating the framework within each individual project leads to duplicated efforts and challenges in maintaining the same version across multiple projects. Hosting the framework on a public CDN can be beneficial for performance and access, but it may not provide the customization and flexibility needed for consistent application across all projects. Creating a standalone JavaScript file does not cater to the comprehensive requirements of styling and layout that are typically addressed by a CSS framework.
