Acceptable Alternatives
When it is not feasible to use this design system (for example, when building a simple web application from scratch), the following design systems/CSS frameworks are acceptable alternatives:
Bootstrap (including derivatives such as Bootstrap-Vue)
Google Material (including derivatives such as Vuetify)
When it is not feasible to customize the design system (for example, when using a prebuilt software like Atlassian Confluence), it is acceptable to use that application's design, assuming all customizable items (such as branding, color scheme, etc.) are compliant with this system.
