The Blazor Puzzle 30 - Why Does Adding a Parameter Break CSS Styling?  @DeveloperExpress
Uploaded April 2024 | Updated September 2026, 2 weeks ago
🧐 The Problem
We have a Blazor Web App (Global Server Everywhere) and we simply add a parameter (ARG) to the home page.
πŸ’₯ Suddenly, all CSS styling disappears!
❌ The navbar, layout, and styles are completely gone
βœ… The parameter still works and updates the message

Commenting out the @page "/{ARG}" line brings the styling back.

πŸ€” The Challenge
Why does adding a parameter break the CSS?

πŸ” Key Clues:
This only happens when a parameter is added to the route
The page still loads, but the styles vanish
Blazor’s router might be interfering with static assets
