/* Changes the readable line length in Obsidian Notes. Tested in Obsidian v0.15.9
See also: https://forum.obsidian.md/t/adjustable-readable-line-length/7564/6

Note: For this the "readable line length" property in settings has to be enabled
(as expected). 700px width is the application's default, adjust all numbers below. 

Pixel (or percentage) as a unit enables a width independent from the number of characters 
(good when adjusting zoom level / font size). For fixed amount of characters use  rem   */
