Grid Ruler

Verry useful for quick measurements or straight alignment.

Vary easy to use! But: 1) ruler show over content - It would be better if roulette was pushing out content. 2) no opportunity to use it with Device Toolbar in chrome developer mode.

Simple to use, does its job perfectly

Apart from the responsive mode bug, this tool is very helpful.

This Tool is very greatest and helpful make a responsive websites in Proper Alignments.

This is a great tool especially if you build websites. Only suggestion would be to add an option where we can select the color of the grid ruler not just light blue, sometimes it's hard to see when the background has bright color.

Its a cool plugin, but it does not work in responsive mode, you cannot click the rulers

I thought I saw this someplace before. I think mah brain had me thinking it was a Chrome feature because I used it in Photoshop to cut up website designs in the 90s. Maybe it was Firefox. Maybe it was an alternative reality or parallel universe. Why isn't this in DevTools already?!!! This is exactly what I need! +1 Grid Ruler Creator +1 !!!

Does exactly as it's meant to, provides guides so you can align elements on a page. Easy to use.

The function to measure the px of a selection of pages is not working well these days.
