On this site you can read a book and add notes wherever you'd like on the side.

The way these pages are styled is by CSS grids, with a .3 fraction column on the left of the 50% width text column, and a 1 fraction column to the right of the text.

You can navigate by the previous and next tabs at the bottom, or by panels on the left and right.

Find War and Peace here and Frankenstein here!
