How to turn off the border at all in the input text?

Question

Docker

it doesn’t work through the focus, or I want to make a blue border, it doesn’t work either

Answer 1

1. Host core.
2. Contains the layers from which the container file system is built, plus metadata, including the launch command. For more details https://docs.docker.com/engine/userguide/storagedr...
3. In debian/ubuntu it is usually /var/lib/docker/.
4 Each command is a new layer, when building a new image, the docker first checks in the cache, if it does not find it or the command has changed, then it builds it again.

Answer 2

outline: none;?
