Grid Ruler

Would be very good if you can add CLEAR button to remove all rulers, Thank You

Verry useful for quick measurements or straight alignment.

Perfect....awesome. Does the job very well

It does its job. I've tried many grid and ruler extensions, just wanting grid lines to check my alignment when doing frontend work. But every other extension tries to force you to make boxes to measure things, when all I needed was alignment and the occasional measurement. This one works perfect. I can get grid lines just like in Photoshop. It hasn't been updated in 10 years apparently, but I've used it my entire career without issues.

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.
