FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Styling Guide
Use Inline Styles (Recommended)
Inline styles are the most reliable way to style HtmlField content:
Tailwind CSS Limitations
Tailwind utility classes (e.g., bg-blue-500, p-4, rounded-lg) will not render unless they are already included in Nova's compiled CSS bundle. Nova only includes the Tailwind classes it uses internally.
Icons and Emojis
HTMLPurifier strips SVG elements by default. Use emoji or Unicode symbols instead:
