I have tried to preview my HTML files within the VS Code GitHub codespace, it worked when it opened in a new tab, but when I opened it directly within VS Code, the content was blocked. I am very certain the cause would be CSP, also known as Content Security Policy. I am trying to a find a solution to this and I have achieved this with an extension called, “Live Server.”

I am using VS Code in my browser via a codespace; due to personal reasons, I cannot install the IDE directly.

I tried an extension called, “InterSystem Extension Pack.” When I initially tried to open it within VS Code; it worked, but then it stopped working.
