Svelte Project in VS Code

Hi! Im new in coding and currently working on my first Svelte-Project. I’m working with a Tutorial.
Now I want to insert the code I have learned into a project in VS Code. My teacher provided me with the basic framework for the project. However, when I insert the code and display the web page, the changes are not displayed. Does anyone have any idea what I am doing wrong? I would be very grateful.

Can you provide more information? Are you trying to deploy the Svelte project on ICP locally or on mainnet?
