Decryption is not related to root permission.
If the ENCRYPTED drive is mounted to the container, then the container can decrypt it.
If the DECRYPTED drive is mounted to the container, then the container never knows it was encrypted in the first place.
Second case is easier BTW. Just mount the drive on your host, type in the encryption password and you get a new, unencrypted drive. Specify this new drive in your docker compose/docker file.
But you dont what the code of the assembly-style centered div in your codebase. Because nobody will be able to read it and understand what it even does. There are abstraction specific ways to solve problems and the right way to do something in assembly is not the right way to do it in CSS.
