Hi

There is an incorrect layout in the table of contents that may lead to reader confusion.

Here is the layout I saw in Chrome (no problem in Chrome on macOS) and Edge on Windows 11 (the -- indicates visual whitespace):

►Programming Interfaces
--►Extensions
----►Features
------►Tools
--------►Advocacy
----------►Technical and Design Documentation
------------►Upgrading SQLite, Backwards Compatibility
--------------►Obsolete Documents

The problem was caused by the following CSS declaration, and it can be solved by removing the clearance for the li element.

.sh_mark {
    float: left;  <--
    width: 1em;
}

regards
