Main Difference between $web container and other containers

Hello,

I am in the process of migrating away from Amazon S3 storage and moving towards Azure Containers with blob storage. My use case for the storage is for online education where we create interactive experiences using Storyline 360. This application publishes our project for web hosting and we used to place these files in S3, make the URL publically available, and then embed it in our learning environment.

[This][1] tutorial was followed for the initial setup. Our workflow was disrupted when our LMS provider informed us that embedded URLs cannot contain certain special characters, like the "$" in our URL. We can work around this by replacing the "$web" with "%24web" in our URLs, but this is not ideal.

I am curious, if we don't need a "static website" and just have to serve some files, can we just simply create a new container and use that? Does the "$web" function as a "root container" and what are the differences between a root container and just a container in general? I have been reading documentation [here][2] and it seems like it is not good practice to have special characters in the container or blob name so why does the first tutorial create one with a special character?

Can anyone explain or point me towards documentation that clearly explains all the differences between the $web container and a regular blob container? I just want to make sure I am doing things according to best practice and in a way that doesn't require URL modification for our LMS.
