The default Obsidian publish theme, has a weird margin for root docs (docs not in subfolders) on the sidebar.

You see it? There's an extra left margin at hey 👋.

To fix this, simply copy paste the CSS below into publish.css in your Obsidian root directory.

div.tree-item-children > div > div:not(.mod-collapsible).is-clickable .tree-item-inner {
	margin-left: -3px;
}

It should fix the CSS for all root docs!
