I'm using getskeleton.com for a responsive website and I'm trying to show the grid lines in the background something like this http://nimb.ws/fTE2AR or http://fearonhay.com/residential/courtyard-house . What would be the best way to accomplish that?
You can turn on the grid button located in the div which has display: grid
declared.
All you have to do is go to your browser's developer tools (mine is Microsoft Edge which is based on Chromium).
You will see a button like this.
And then you can code and test as you wish.
