Pixel ruler in Chrome?

Question

Google Chrome

Hello.
This morning I discovered that when inspecting an element in Google Chrome, a pixel ruler appeared.
It was always there and I didn’t know how to turn it on, or is it a super-important and convenient update that others don’t have, and which should be talked about?
Thank you!

Answer 1

Yes, I also noticed a ruler a couple of days ago, it didn’t seem to exist before, I think it’s an extremely useful tool for layout designers.

Answer 2

Yeah, an innovation, but I don’t see convenience in it

Answer 3

And how to start/enable this line?

Answer 4

I wish there were some guides attached to it.

Answer 5

I began to check and the hair moved on the navel - the load on the percent jumped noticeably.
A convenient and useful tool, but the introduction of such a voracious part into a stable version of the browser is somehow scary ... Something is wrong in the testing process.
Version 23.0.1271.64 Ubuntu 12.04

Answer 6

I think that this is some kind of update, since it also appeared suddenly, but it didn’t exist before. And I don’t see how to remove it - it prevents screenshots from being taken.

Answer 7

In the current stable version 23, the inability to disable the ruler is described in the bug report .
Will be fixed in the new version. Or use unstable 25 version.
