Question

Google Chrome

Are there any tools/plugins for chrome and firefox that can display a custom grid on top of the page? I found some kind of poor plugin for chrome - the grid is thick, the parameters are not set, I deleted it. The rulers along the edges of the page are not always satisfactory, I just want a grid so that I can change the color and thickness of the lines, the distance between the lines.

Answer 1

I found it myself by brute force - Toggle rulers - what you need!

Answer 2

Very handy tool
