Based on this script:
https://greasyfork.org/en/scripts/372448-reading-ruler/code
This reading ruler will aid you on reading texts on the internet
It will place a semi-transparent line on your screen, just hit the combination ctrl + r on windows and mac (not the command button but the control button) to activate the ruler, hit the same configuration to remove the ruler
This idea come from the reddit user /u/VectorLightning

It is the only ruler that works for my online textbooks, and I like how it changes size depending on the text. The color is not too bright but is still easily noticeable, and it doesn't affect the mouse function.
This app is an awesome idea, but the ruler doesn't work lately sadly.
