inside container.

Hello. since the new version of generate block comes out, I am trying to update my page.

I am trying to use tab block for this.

The first one is the original one that I will remove once I make the same thing with tab block.

when you scroll down, you can see what I am making.

but the size of container is too broad and i don't know how to reduce it. I already made inside container with the new function.
