About Site Settings
The "Settings" button is located in top center or top right corner of every page. Clicking it will open the "Site Settings" panel. This panel contains buttons to control various settings for this website.
Brightness Controls
The brightness of the screen is controlled by changing the background color of the webpage. When you visit this website for the first time, the background color will be of moderate brightness. You can adjust the brightness so that it better suits you.
The "Lighter Background" button will make the screen bright by increasing the light in the background of the text.
The "Darker Background" button will make the screen less bright by decreasing the light in the background of the text.
When the background becomes dark, the text appears in lighter color. When the background becomes bright, the text appears in darker color. When one presses the "Lighter Background" button when already at the brightest setting, the setting switches to the moderate brightness setting. When one presses the "Darker Background" button when already at the darkest setting, the setting switches to the moderate setting.
Font Size Controls
When you first visit this website, the font size of the displayed text is the regular size of the text. You can adjust the font size so that it better suits you.
The "Smaller Font" button will reduce the font size. It can only be reduced to half the default size.
the "Larger Font" button will increase the font size. It can only be increased to twice its default size.
When one presses the "Smaller Font" button when already at the smallest setting, the font size switches to the regular size. When one presses the "Larger Font" button when already at the largest setting, the font size switches to the regular size.

Pressing the "Previous Font" button will switch the font of the displayed text to the previous font.
Pressing the "Next Font" button will switch the font of the displayed text to the next available font.
If one presses the "Previous Font" button when at the first font, the last font is chosen. If one presses the "Next Font" button when at the last font, the first font is chosen.

Other Settings and Controls
The buttons "Cols++" and "Cols--" changes the number of columns in which the contents of the chapter are presented.
Each chapter can be viewed in one of two Chapter View Modes and the default view mode for all books can be set here. Further information is in the chapter "About Chapter Pages".
Chapters have additional controls. These Chapter Controls can be hidden or shown be pressing the Escape key, or by pressing the "Show/Hide Chapter Controls (Esc)" button. This button in site settings is useful to show chapter controls when they are hidden and the viewing device lacks a keyboard.
Settings are stored in Local Storage
The site settings apply to almost all pages of this website. When you navigate from one page to next, the settings that you chose on one page are preserved when you go to the next page.
These settings are preserved because they are stored in "local storage" in your web browser; not on this website. When you close the browser or the tab, the "local storage" is not discarded by your browser. When you visit this website again, all your previous settings are still there.
Note that "local storage" is not the same as "cookies".
