Publish - change the position of components

Hello Obsidian community,

Does anybody know how to customize the position and size of components on your obsidian publish ?

  1. I’m looking to remove the left side bar, and divide the screen in half between the note and graph views.

All the obsidian publish websites I stumble upon have the same component disposition, except for the LYT Kit one: + Start Here - LYT Kit (@nickmilo ). The side bar is removed, the search bar on top and no graph.

Can I achieve this only by manipulating the publish.css ? Or do I also need some javascript code ?

I also would like to know how elements can be arranged differently.
