This question already has an answer here:

I'm working with CSS and at times it's hard to see if something's centred. Is there a program or some way built into a browser that I can make a grid appear on the screen? I'm using FireFox on Windows 7 but I'm willing to try a different browser.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

I use the edge of a piece of paper, or a ruler. :) – Ƭᴇcʜιᴇ007 Mar 5 '13 at 18:36
There was absolutely no basis to close this question as an on-screen ruler meant for various purposes and a grid built into a browser to facilitate web design and CSS coding is not the same thing. – Desmond Hume Mar 6 '13 at 10:38
@DesmondHume that may be true but this question is still Off-Topic as it's a software rec. – KronoS Mar 6 '13 at 19:25
@KronoS some problems inherently require a software solution, even you admit it…. If you know a solution that doesn't require software feel free to suggest it. – Celeritas Mar 6 '13 at 19:45
@Celeritas this is true, and I'm in no way saying that ALL questions that require software as a solution are off-topic. At quick glance your question appeared to be asking "what's the best app to do x". Upon closer examination I see that you're looking for a solution to a problem and not a query for "what's the best..." – KronoS Mar 6 '13 at 19:49

GridFox seems to be one of few solutions for this, or possibly the only one in existence.

It used to save gird setting for each domain but this feature is no longer working since the server it was saving settings to is down. So, to let GridFox make grids and save any settings, you'll have to go to Tools > GridFox > Preferences and check "Don't save grids for each domain" checkbox.

Thanks, do you know if there's a way to set it so that the grid is made of squares? Or do I have to play with the settings until I guess it right? – Celeritas Mar 6 '13 at 17:58

You could always make a transparent image with two edges colored and then tile it across the whole page with CSS while you're working on it. You'll have to add it to every page and then remove it when you're done, but it's a pretty easy solution.
