I don't believe so.
I thought there used to be a grey line, if you wrote so many underscores, which was horizontal and went from one sides of the screen to the other whether on a mobile or computer. If thats what you mean by signatures then sure.Also, BTW all I can see on your comment is some text *(You mean, ...)*and then a few lines down more text (like that). Just saying in case there was meant to be anything more there.
Also recently discovered how to change font size, not sure if thats common knowledge but its very subtly done, bravo!
HHC-
Your screen contrast may be too low, and your screen brightness too high.
There are horizontal rules... but it sounds like they are washed out on the device/screen that you are viewing this on.
You may want to use a calibration pattern to adjust whatever settings are available to you:
